(A) Heating of 3,6-dichloropyridazine (I) with hydrazine hydrate at 100 C gives 6-chloro-3-pyridazinylhydrazine (II). The hydrazino group is protected by transforming it with camphor (III) to the camphorhydrazone (IV), which is aminated by heating with morpholine to give the morpholinylhydrazone (V). After liberating the hydrazine function by acidic hydrolysis in a biphasic system, the resulting 6-morpholino-3-pyridazinylhydrazine (VI) is reacted either with tert-butylacetoacetate (VII) or with tert-butylpropiolate (VIII) to yield RGH-5526.

(X) Delmopinol can be obtained by three different ways:
1) The reaction of 2-(benzylamino)-6-propylnonan-1-ol (I) with ethylene oxide (II) in ethanol at 100 C yields the corresponding N-(2-hydroxyethyl)derivative (III), which is cyclized with H2SO4 at 140-150 C to 4-benzyl-3-(4-propylheptyl)morpholine (IV). The debenzylation of (IV) by hydrogenolysis with H2 over Pd/C affords the free morpholine (V), which is finally condensed with 2-chloroethanol (VI) by means of KI and KOH in refluxing ethanol.
2) The Grignard condensation of 4-heptanone (VII) with allyl bromide (VIII) in ethyl ether gives 4-propyl-1-hepten-4-ol (IX), which is cyclocondensed with morpholine (X) by means of H2O2 and Na2WO4 in methanol to yield 4-(perhydroisoxazol[3,2-c][1,4]oxazin-2-ylmethyl)-4-heptanol (XI). Reductive ring opening of (XI) by hydrogenation with H2 over Pd/C and p-toluenesulfonic acid in isopropanol affords a mixture of the morpholine (V) and the hydroxymorpholine (XII). This mixture, without separation, is treated first with SOCl2 in chloroform to perform Cl-OH interchange, then with NaOH to obtain the corresponding double bond, and finally, the mixture is hydrogenated with H2 over Ra-nickel and triethylamine in dioxane in order to obtain pure (V), already obtained.
3) The acylation of the alkylmorpholine (V) with oxalic acid monomethyl ester (XIII) by means of triethylamine in refluxing benzene gives the corresponding condensation compound (XIV), which is then reduced with LiAlH4 in refluxing ethyl ester.

(A) The reaction of bicyclo[3.2.0]hept-2-en-6-one (I) with 1,3-dibromo-5,5-dimethylhydantoin (DBDMH) in acetic acid gives 3-endo-acetoxy-2-exo-bromo-bicyclo[3.2.0]heptan-6-one (II), which is treated with morpholine in dichloromethane to yield 5-endo-acetoxy-7-anti morpholinobicyclo[2.2.l]heptan-2-one (III). Hydrolysis of (III) with NaOH gives the norbornanone (IV), which is alkylated with biphenyl methylbromide under phase transfer catalysis to give 5-endo[(1,1'-biphenyl)-4 yl]methoxy-7-anti-morpholinobicyclo[2.2.1]heptan 2-one (V). Baeyer-Villiger oxidation followed by partial reduction with diisobutylaluminum hydride (Dibal) gives the aldehyde (VI), which is then homologated to the aldehyde (VII) using methoxymethylenetriphenyl phosphorane and subsequent treatment with 2N HCl. Condensation of (VII) with 3 carboxypropyl triphenylphosphorane in tetrahydrofuran affords the acid (VIII). Finally, this compound is oxidized with Jones' reagent.

(C) The starting 3-fluorothiophenol (I) is obtained either from 3-fluoro-1-bromobenzene (II) by reaction with Mg and a following treatment with S, or from 3-fluoroaniline (III) by the Leuckart method via 3-fluorobenzenediazonium xanthate and 3-fluorophenyl xanthate.
Two different ways were described for obtaining the acid (VI):
1) Reaction of (I) with 5-chloro-2-iodobenzoic acid (A) in a boiling aqueous KOH solution in the presence of Cu, which leads to the acid (IV). This is transformed in three steps (reduction with sodium dihydrodibis(2-methoxyethoxy)aluminate, followed by reaction with SOCl2 in pyridine, and final reaction with NaCN in boiling aqueous ethanol) to the nitrile (V), which is hydrolyzed with a boiling solution of KOH in aqueous ethanol.
2) Reaction of (I) with 2,5-dichloro acetophenone (B) in dimethylformamide at 150 C in the presence of Cu. The resulting ketone (VII) is proceased by the Kindler's modification of the Willgerodt reaction: treatment with S in boiling morpholine (C) gives the thiomorpholide (VIII), which is hydrolyzed either with a boiling ethanolic KOH solution or with a refluxing mixture of dilute H2SO4 and acetic acid.
The acid (VI), obtained by both routes, is cyclized with polyphosphoric acid at 150 C to the ketone (IX), which is reduced with sodium borohydride in aqueous ethanol to the alcohol (X). Treatment with HCl in benzene in the presence of CaCl2 affords the reactive chloride (XI), which can be converted to the final product (XIV) by two methods:
(b) substitution reaction of (XI) with 1-(ethoxycarbonyl)piperazine (D), followed by alkaline hydrolysis of the carbamate (XII) and addition of the secondary amine (XIII) to acrylamide in tert-butyl alcohol in the presence of benzyltriethylammonium hydroxide.
(a) substitution reaction with 3-(1-piperazinyl)propionamide (E) in boiling chloroform gives directly (XIV);

(B) By reaction of ethyl 2-fluoro-4-biphenylylacetate (I) first with diethyl carbonate and sodium ethoxide, and then with dimethyl sulfate in ethanol to give diethyl 2-fluoro-4-biphenylyl-alpha-methylmalonate (II), which was hydrolyzed with NaOH in ethanol and finally decarboxylated at 180-200 C.
The starting product (I) was obtained as follows: the Ullman condensation of 4-bromo-3-nitroacetophenone (III) gives 2-nitro-4-acetylbiphenyl (IV), which was reduced to the corresponding amino compound (V). This, by the Schieman reaction was converted into 2-fluoro-4-acetylbiphenyl (VI), which by heating with sulfur and morpholine (B) gave 2-fluoro-4-biphenylylacetic acid (VII), and finally (VII) was esterified by refluxing with ethanol and H2SO4.

(VIII) 1) Synthesis of N(tau)-tert-butoxycarbonyl-N(alpha)-[2(R)-(morpholinocarbonylmethyl)-3-(1-naphthyl)propionyl]histidine:
The condensation of diethyl succinate (III) with 1-naphthaldehyde (IV) by means of sodium ethoxide in refluxing methanol gives 2-(1-naphthylmethylene)succinic acid diethyl ester (V), which is hydrolyzed to the corresponding acid (VI) with NaOH. The cyclization of (VI) with refluxing SOCl2 affords the anhydride (VII), which is treated with morpholine (VIII) in ethyl acetate, yielding 2-(morpholinocarbonylmethyl)-3-(1-naphthyl)acrylic acid (IX). Hydrogenation of (IX) with H2 over Pd/C in methanol affords the corresponding propionic acid (X), which is then condensed with histidine methyl ester (XI) by means of DCC and HONB as before, giving a racemic mixture that is submitted to optical resolution by repeated crystallization of its salycylic acid salt, thus yielding N-[2(R)-(morpholinocarbonylmethyl)-3-(1-naphthyl)propionyl]histidine methyl ester (XII). Finally, this compound is hydrolyzed with NaOH and protected with tert-butoxycarbonyl anhydride to give (I).

(XV) Alternatively, intermediate (XIII) can be obtained as follows: Heating of ethyl (S)-lactate (XIV) with morpholine affords amide (XVI), which then reacts with 3,4-dihydro-2H-pyran (A) in the presence of p-TsOH to give protected derivative (XVII). Grignard reaction between (XVII), bromo derivative (XVIII) and Mg turnings in THF yields protected ketone (XIX), which is treated with pyridinium p-toluenesulfonate (PPTS) (THP group removal) and reprotected by means of Tf2O and DIEA to give triflate derivative (XX). Conversion of (XX) into intermediate (XIII) is achieved by reaction with triazolone (VII) and NaH in THF.

(XI) Acylation of 1-acetyl-1,2,3,4-tetrahydroquinoline (I) with 2-chloropropionyl chloride (II) by means of AlCl3 provides the quinoline derivative (III), which is deacetylated by treatment with HCl to give 1,2,3,4-tetrahydro-6-(2-chloropropionyl)quinoline (IV). Condensation of compound (IV) with O-ethyl hydrazinethioformate (V) in refluxing acetonitrile yields the thiadiazinone (VI), which is then N-acylated at the quinoline ring with 3,4-dimethoxybenzoyl chloride (VII) by means of Et3N in methylene chloride to give the racemate EMD-53998 [rac-(VIII)]. Optical resolution of EMD-53998 can be performed by two different ways: a) enantioseparation via chromatography with Chiralpak AD in 100% EtOH as eluent and b) acylation of EMD-53998 with (S)-camphanoyl chloride (IX) by means of Et3N in methylene chloride followed by treatment with morpholine in the same solvent to afford a mixture of ()-EMD-53998 (EMD-57439) and the camphanoyl amide (X), which are separated by chromatography. Finally, the (+)-enantiomer, EMD-57033, is isolated by further treatment of amide (X) with morpholine in methylene chloride.

(XI) 4-Amino-1-benzylpiperidine (II) was acylated with 5-methyl-2-nitrobenzoyl chloride (I) to afford the ortho-nitrobenzamide (III), which was reduced to the amino derivative (IV) by catalytic hydrogenation in the presence of Pd/C. Treatment of (IV) with ethyl chloroformate produced the bis-carbamate (V) with concomitant cleavage of the N-benzyl group. This was cyclized to the dioxoquinazoline (VI) upon treatment with KOH in refluxing EtOH. After N-methylation employing iodomethane and NaH in DMF, hydrolysis of the carbamate group with concentrated HBr yielded the piperidinylquinazoline (VIII). This was then condensed with 2,4-dichloro-6,7-diethoxyquinazoline (IX) to furnish adduct (X). Finally, displacement of the remaining chlorine of (X) with morpholine (XI) in hot NMP gave rise to the title compound.

(XI) Nitration of chromanone (I) with fuming HNO3 at -35 C afforded 6-nitro-4-chromanone (II). Subsequent aldol condensation of (II) with glyoxylic acid (III) in the presence of H2SO4 produced the alpha-beta-unsaturated acid (IV). Further hydrogenation of the nitro, keto, and olefin groups of (IV) with concomitant esterification produced the benzopyranylacetate (V). After protection of (V) as the N-Boc derivative (VI), optical resolution was achieved by preparative HPLC on a Chiralcel-OD column. The desired (S)-enantiomer (VI) was deprotected using ethanolic HCl to afford amine (VII), which was condensed with 4-cyanobenzoyl chloride (VIII) to give amide (IX). Treatment of (IX) with HCl-EtOH produced imidate (X), and subsequent treatment with morpholine (XI) furnished the target amidine, which was isolated as the hydrochloride salt.

(II) The condensation of (R)-lactic acid (I) with morpholine (II) gives the corresponding morpholide (III), which is protected at the hydroxyl position with dihydropyran (IV) to yield the tetrahydropyranyl ether (V). The Grignard reaction of (V) with 2,4-difluorophenylmagnesium bromide (VI) affords the chiral 1-propanone (VII), which by a Corey's diastereoselective epoxidation with trimethylsulfoxonium iodide is converted into the oxirane (VIII). The opening of the oxirane ring of (VIII) by means of 1,2,4-triazole (IX) and NaH provides the tertiary alcohol (X), which is treated with pyridine p-toluenesulfonate to give the deprotected diol (XI) as a (2R,3R) and (2R,3S) 4:1 diastereomeric mixture, from which the desired (2R,3R)-isomer (XII) was isolated by crystallization. The reaction of (XII) with Ms-Cl and TEA, followed by cyclization with NaOMe, yields the oxirane (XIII), which is finally condensed with 7-chloroquinazolin-4(3H)-one (XIV) by means of K2CO3 in hot NMP.

(XI) Nitration of chromanone (I) with fuming HNO3 at -35 C afforded 6-nitro-4-chromanone (II). Subsequent aldol condensation of (II) with glyoxylic acid (III) in the presence of H2SO4 produced the alpha-beta-unsaturated acid (IV). Further hydrogenation of the nitro, keto, and olefin groups of (IV) with concomitant esterification produced the benzopyranylacetate (V). After protection of (V) as the N-Boc derivative (VI), optical resolution was achieved by preparative HPLC on a Chiralcel-OD column. The desired (S)-enantiomer (VI) was deprotected using ethanolic HCl to afford amine (VII), which was condensed with 4-cyanobenzoyl chloride (VIII) to give amide (IX). Treatment of (IX) with HCl-EtOH produced imidate (X), and subsequent treatment with morpholine (XI) furnished amidine (XII). Finally, basic hydrolysis of the ester function provided the target amidinoacid, which was isolated as the hydrochloride salt.

The intermediates benzopyran (VI) and morpholine (XVI) have been obtained as follows:
Benzopyran (VI): The reaction of 8-methoxy-4H-1-benzopyran-3-carboxylic acid (I) with SOCl2 in refluxing toluene gives the acyl chloride (II), which is condensed with morpholine (III) in dioxane yielding the methanone (IV). The reaction of (IV) with BBr3 in dichloromethane affords the 1-(8-hydroxy-2H-1-benzopyran-3-yl)-1-(4-morpholinyl)methanone (V), which is reduced with LiAlH4 in THF giving the desired intermediate benzopyran (VI).
Morpholine (XVI): The reaction of benzyl (S)-glycicyl ether (VII) with benzylamine (VIII) gives 1-(benzylamino)-3-(benzyloxy)-2(R)-propanol (IX), which is cyclized with chloroacetyl chloride (X) and triethylamine in dichloromethane yielding the morpholinone (XI). The reduction of (XI) with LiAlH4 in ethyl ether affords the fully protected morpholine (XII), which is debenzylated with H2 over Pd/C in ethanol giving 2(R)-(hydroxyethyl)morpholine (XIII). The reaction of (XIII) with trityl chloride (XIV) and TEA in dichloromethane yields the N-tritylmorpholine (XV), which is finally tosylated with tosyl chloridde and pyridine affording the desired intermediate morpholine (XVI).

(IX) The known diarylimidazole (I) was protected as the N-[2-(trimethylsilyl)ethoxy]methyl derivative (II) by treatment with 2-(trimethylsilyl)ethoxymethyl chloride and NaH. Lithiation of (II) with BuLi at -78 C, followed by quenching with N-formylmorpholine (III) provided aldehyde (IV). This was converted to the dimethyl acetal (V) upon treatment with trimethyl orthoformate and p-toluenesulfonic acid. Further condensation of (V) with methyl 2,2-bis(hydroxymethyl)propionate (VI) produced the dioxane derivative (VII) as a mixture of cis and trans isomers. Basic hydrolysis of the methyl ester group of (VII) afforded the corresponding carboxylic acid. The desired trans isomer (VIII) was then isolated by selective precipitation of the acidified methanolic solution. Finally, coupling of (VIII) with morpholine (IX) using EDC and HOBt furnished the title amide.

(IX) DPC-961 (I) can be obtained by several different related ways:
1) Condensation of 2'-amino-5'-chloro-2,2,2-trifluoroacetophenone (II) with trimethylsilyl isocyanate in the presence of dimethylaminopyridine in THF, followed by desilylation with tetrabutylammonium fluoride in THF, provides the quinazoline derivative (III), which is dehydrated employing molecular sieves in refluxing toluene to yield the imine (IV). Treatment of compound (IV) with lithium cyclopropylacetylide (V) in THF in the presence of BF3.Et2O gives the racemic adduct (VI). Finally, the desired (S)-enantiomer (I) is isolated by means of chiral HPLC .
2) Condensation of 6-chloro-4-(trifluoromethyl)quinazolin-2(1H)-one (IV) with lithium cyclopropylacetylide (V) catalyzed by the chiral auxiliary (X) in toluene/THF gives directly DPC-961. The chiral auxiliary (X) can be synthesized as follows: Epoxidation of (+)-3-carene (VII) with MCPBA in dichloromethane gives the corresponding epoxide (VIII), which is then condensed with morpholine (IX) by means of MgBr2 as catalyst.

(II) The condensation of 4-chloro-2,6-pyridinedicarboxylic acid (I) with morpholine (II) afforded the morpholinopyridinedicarboxylic acid (III), which was further esterified with MeOH and HCl to produce diester (IV). Reduction of (IV) with NaBH4 and CaCl2 gave hydroxy ester (V). After protection of the hydroxyl group of (V) as the trimethylsilylethoxymethyl derivative (VII), the ester group was hydrolyzed under basic conditions yielding acid (VIII). This was then subjected to a Curtius rearrangement with DPPA in the presence of tert-butanol to generate the tert-butyl carbamate (IX). Alkylation of carbamate (IX) with 3-methoxy-5-nitrobenzyl bromide (X) and NaH furnished the N-benzyl carbamate derivative (XI). The nitro group of (XI) was then reduced to amine (XII) by catalytic hydrogenation over Pd/C.

(II) A similar method, but using a different protection strategy, has been reported. 4-Hydroxy-2,6-pyridinedicarboxylic acid (XVIII) was condensed with morpholine (II) to provide, after Fischer esterification, the morpholinopyridine diester (IV). Reduction of (IV) with calcium borohydride furnished hydroxy ester (V). Protection of (V) as the corresponding tetrahydropyranyl ether, followed by ester group saponification, afforded (XIX). Curtius rearrangement of acid (XIX) in the same conditions as above gave carbamate (XX), which was alkylated with benzyl chloride (XXI) yielding (XXII). After reduction of the nitroderivative (XXII) with iron and ammonium chloride, the resultant amine (XXIII) was acylated by allyl chloroformate to produce carbamate (XXIV). Then, acidic treatment removed the tetrahydropyranyl-protecting group to afford alcohol (XIV), which was finally processed as in the above method.

(XI) 2-Bromoaniline (VIII) is acylated by bromoacetyl chloride (IX) in pyridine to produce the corresponding bromoacetanilide (X). Subsequent displacement of the aliphatic bromide of (X) with morpholine (XI) furnishes the morpholinoacetanilide (XII). Alkylation at the amide N of (XII) with iodomethane and NaH leads to the N-methyl amide (XIII). Stille coupling of aryl bromide (XIII) with tributyl (1-ethoxyvinyl)tin (XIV) yields the enol ether (XV). Bromination of enol ether (XV) with N-bromosuccinimide in moist THF produces the bromo acetophenone (XVI), which is further reacted with NaN3 to give the azido ketone (XVII). The target amino oxazole compound is finally obtained by condensation of azido ketone (XVII) with isothiocyanate (VII) in the presence of PPh3 in hot dioxane.

(XIII) In a related synthetic strategy, acylation of 2-bromoaniline (I) with acetoxyacetyl chloride (II) affords the acetoxy acetanilide (III). Alkylation of amide (III) with iodomethane and NaH leads to the N-methyl amide (IV). Then, Stille coupling of aryl bromide (IV) with tributyl (1-ethoxyvinyl)tin (V) gives rise to the enol ether (VI). Bromination of (VI) with N-bromosuccinimide in moist THF, followed by displacement of the resultant bromo ketone (VII) with NaN3 provides azido ketone (VIII). The key oxazole (X) is then obtained by condensation of azido ketone (VIII) with isothiocyanate (IX) in the presence of PPh3. Alkaline hydrolysis of the acetate ester (X) yields alcohol (XI), which is converted to mesylate (XII) by means of methanesulfonyl chloride and triethylamine. The mesylate group is finally displaced with morpholine (XIII) to furnish the title compound.

(VII) Fischer esterification of 4'-hydroxybiphenyl-4-carboxylic acid (I) with H2SO4/MeOH provides ester (II). The phenolic hydroxyl group is then alkylated with 1-bromo-3-chloropropane (III) in the presence of K2CO3 to furnish the chloropropyl ether (IV). Saponification of methyl ester (IV) with LiOH leads to carboxylic acid (V), which is further activated as the corresponding acid chloride (VI) upon heating in SOCl2. Acid chloride (VI) is subsequently coupled with morpholine (VII) to yield amide (VIII). Finally, alkyl chloride (VIII) is displaced with (R,R)-2,5-dimethylpyrrolidine (IX) in the presence of K2CO3 and KI to furnish the title compound.

(XIV) Alkylation of vanillic acid methyl ester (V) with 3-chloropropyl tosylate (VI) in the presence of K2CO3 and Aliquat 336 gives the chloropropyl ether (VII). Subsequent electrophilic nitration of (VII) in hot HOAc affords the ortho-nitrobenzoate (VIII), which is further reduced to the amino benzoate analogue (IX) employing Fe/NH4Cl. Condensation of amino ester (IX) with dimethylformamide dimethylacetal provides adduct (X). This is then converted to the key quinoline derivative (XI) upon condensation with acetonitrile in the presence of butyllithium. Chlorination of (XI) with boiling POCl3 leads to the 4-chloroquinoline (XII). This is then coupled with the (imidazolylsulfanyl)aniline (IV) using pyridinium chloride in refluxing ethoxyethanol to furnish the anilino quinoline adduct (XIII). Finally, displacement of the chloride group of (XIII) with morpholine (XIV) in DMF provides the title compound.

(XIX) The precursor dihydropyridones (IIa) and (IIb) can be synthesized as follows. Acylation of either 4-nitroaniline (XVa) (1) or 4-iodoaniline (XVb) (2) with 5-bromovaleryl chloride (V) affords the corresponding bromoamides (XVIa) and (XVIb), which are cyclized to piperidones (XVIIa) and (XVIIb) upon treatment with potassium tert-butoxide or with potassium hydroxide under phase-transfer conditions. Piperidones (XVIIa/b) are then chlorinated by means of phosphorus pentachloride in chlorobenzene or chloroform to form the geminal dichlorides (XVIIIa) and (XVIIIb) (1, 2). Dehydrohalogenation of (XVIIIa) by means of lithium carbonate and lithium chloride in DMF at 105-110 °C then provides the chloro dihydropyridone (IIa) (1). Alternatively, the dichloro derivative (XVIIIb) is refluxed with neat morpholine (XIX) to furnish intermediate (IIb) (2). Scheme 3.

(V) Cyclization of morpholine-4-carboximidamide hydrobromide (I) with diethyl malonate (II) by means of naoEt in refluxing EtoH gives 2-(morpholin-4-yl)pyrimidine-4,6-diol (III), which by chlorination with PoCl3 at 120 °C affords 4,6-dichloro-2-(morpholin-4-yl)pyrimidine (IV). nucleophilic substitution of the dichloropyrimidine (IV) with morpholine (V) in the presence of Et3n in refluxing N-methyl-2-pyrrolidone provides 2,4-di(morpholin-4-yl)-6-chloropyrimidine (VI) . Alternatively, dimorpholinopyrimidine (VI) is prepared by reaction of 2,4,6-trichloropyrimidine (VII) with morpholine (V) in THF, followed by chromatographic separation . Finally, chloropyrimidine derivative (VI) is submitted to a Suzuki cross-coupling reaction with boronate ester (VIII) in the presence of Pd(dppf)2Cl2·CH2Cl2 or Pd(dppf)2Cl2 and na2Co3 in 1,2-dimethoxyethane at 90-95 °C .
Alternatively, iodination of chloride (VI) with HI and naI yields the corresponding iodide (IX) , which is also coupled with boronate (VIII) in the presence of Pd(dppf)Cl2·CH2Cl2 and K2Co3 in 1,4-dioxane/H2o at 100 °C .
Boronate ester (VIII) is obtained by bromination of 4-(trifluoromethyl) pyridin-2-amine (X) with nBS in CHCl3 or CH2Cl2 to afford 5-bromo-4-(trifluoromethyl)pyrimidin-2-amine (XI), which is finally condensed with bis(pinacolato)diboron (XII) in the presence of Pd(dppf)2Cl2·CH2Cl2 and KoAc in refluxing dioxane or DMSO .

(V) Cyclocondensation of ethyl 3-amino-4-methyl-2-thiophenecarboxylate (I) with urea (II) at 190 °C gives 7-methylthieno[3,2-d]pyrimidine-2,4-dione (III), which is chlorinated with POCl3 at reflux to yield 2,4-dichloro-7-methylthieno[3,2-d]pyrimidine (IV). Condensation of compound (IV) with morpholine (V) in MeoH affords 2-chloro-7-methyl-4-(4-morpholinyl)thieno[3,2-d]pyrimidine (VI) , which, after metalation with BuLi in THF, is formylated with DMF, providing the thieno[3,2-d]pyrimidine-6-carbaldehyde derivative (VII) . Reductive amination of aldehyde (VII) with N-Boc-piperazine (VIII) in the presence of HC(oMe)3, AcoH and naBH(oAc)3 in dichloroethane gives the piperazinylmethyl derivative (IX) , which by cleavage of the Boc moiety by means of HCl in CH2Cl2 produces the N-deprotected piperazine derivative (X). N-Acylation of compound (X) with (S)-lactic acid (XI) in the presence of HATU and DIEA in DMF generates the corresponding amide (XII), which is finally submitted to Suzuki coupling with the boronate ester (XIII) in the presence of PdCl2(PPh3)4 and Na2CO3 or K2CO3 in acetonitrile .
Alternatively, Suzuki coupling of chloro intermediate (IX) with boronate ester (XIII) in the presence of PdCl2(PPh3)2 and Na2CO3 in acetonitrile under microwave irradiation produces the 2-aminopyrimidine derivative (XIV), which is then N-deprotected by means of HCl in CH2Cl2 to yield the free piperazine derivative (XV). Finally, piperazine derivative (XV) is condensed with (S)-lactic acid (XI) in the presence of DIEA and HATU in DMF .

(XXVII) N-Protection of 2-amino-5-nitrophenol (XVII) with Ac2O in the presence of AcOH gives N-(2-hydroxy-4-nitrophenyl)acetamide (XXI), which upon O-alkylation with ethyl bromide (XX) in the presence of K2CO3 in DMF at 60 °C affords N-(2-ethoxy-4-nitrophenyl) acetamide (XXII). Reduction of the nitro derivative (XXII) with H2 over Pd/C in THF furnishes the corresponding aniline (XXIII), which by condensation with ethyl 2-cyano-3-ethoxy-2-propenoate (XXIV) at reflux produces enamine (XXV). Thermal cyclization of enamino ester (XXV) in Dowtherm at 250 °C then yields 4-hydroxyquinoline derivative (XXVI) , which upon chlorination with POCl3 in 1,2-diethoxyethane at 80-85 °C affords N-(4-chloro-3-cyano-7-ethoxyquinolin-6-yl)acetamide (VII) .

(II) Condensation of the chloroacetyl tripeptide (I) with morpholine (II) by means of KI in THF gives the tetrapeptide derivative (III), which is hydrolyzed with LiOH in MeOH/H2O to yield the corresponding carboxylic acid (IV) . Alternatively, reaction of the trifluoroacetate salt of tripeptide (V) with 4-morpholinoacetic acid (VI) in the presence of DIEA and PyBOP in DMF affords the tetrapeptide benzyl ester (VII), which is then debenzylated by means of H2 over Pd/C in MeOH/EtOAc to give the carboxylic acid (IV) . Finally, the carboxylic acid building block (IV) is coupled with either 2(S)-amino-4-methyl-1-[2(R)-methyloxiran-2-yl]pentan-1-one trifluoroacetate salt (VIII) in the presence of DIEA, HOBt and PyBOP in acetonitrile , or BOP in DMF, or HBTU in DMF or acetonitrile , or with the formic acid salt (IX) by means of DIEA, HOBt and HBTU in acetonitrile . The corresponding citrate salt is prepared by treatment of carfilzomib with citric acid in THF .
