(III) 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);

(XI) The title compound was synthesized by two related procedures. 3-Fluoro-N-methylaniline (XIV) was obtained from 3-fluoroaniline (XI) by condensation with 1-(hydroxymethyl)benzotriazole (XII), followed by reduction of the anilinomethylbenzotriazole (XIII) with NaBH4. Subsequent condensation with 3-formylbenzoyl chloride (XV) (prepared from the corresponding acid and SOCl2) provided amide (XVI). Then, condensation of (XVI) with piperazine (V) and benzotriazole in the presence of a catalytic amount of Et3N in refluxing toluene furnished (XVII) as a mixture of epimers. 3-Bromophenol (XVIII) was protected as the silyl ether (XIX) with tert-butyldimethylsilyl chloride and imidazole. This compound was converted to the organolithium derivative with n-butyllithium in THF at -78 C, and further transformed to the arylmagnesium reagent (XX) by treatment with magnesium bromide etherate in THF. Condensation of (XVII) with organometallic compound (XX) afforded the benzhydrylpiperazine (XXI) as a 10:1 mixture of epimers. Desilylation of (XXI) by treatment with HCl in aqueous THF, followed by recrystallization of the major isomer from EtOAc/hexane yielded the title compound.

(I) Reaction of 3-fluoroaniline (I) with formic acid gave formanilide (II), which was reduced by means of LiAlH4 to afford 3-fluoro-N-methylaniline (III). Further alkylation of (III) with benzyl chloride provided the tertiary amine (IV). Vilsmeier-Haack formylation of (IV) with POCl3 and DMF yielded aldehyde (V), which was condensed with nitroethane in the presence of ammonium acetate to give the 2-nitropropene derivative (VI). After reduction of (VI) to the amine (VII) with LiAlH4, condensation with chloroacetyl chloride afforded chloracetamide (VIII). Subsequent displacement of the chlorine of (VIII) with dibenzylamine yielded the tertiary amine (IX). Finally, hydrogenolytic debenzylation of (IX) in the presence of Pd/C furnished the title compound.

The cyclization of the carbamate (VIII) with (S)-3-chloropropane-1,2-diol (IX) by means of Li t-amylate in DMF gives the oxazolidinone (X), whose free OH group is activated with 2,5-dichlorobenzenesulfonyl chloride (XI) and TEA in dichloromethane to yield the sulfonate (XII). The reaction of (XII) with NH4OH in methanol/acetonitrile affords the aminomethyl derivative (XIII), which is finally acylated with acetic anhydride (XIV) to provide the target sulfoxide.

(I) Condensation of 3-fluoroaniline (I) with the cyclic anhydride (II) in AcOH gave amide (III). Subsequent cyclization of (III) in hot H2SO4 produced quinolineacetic acid (IV). After esterification of (IV) with methanol in the presence of SOCl2, the resulting methyl ester (V) was reduced to alcohol (VI) using NaBH4 in refluxing THF. Treatment of alcohol (VI) with SOCl2 afforded chloride (VII), which was condensed with 4-(1-piperazinyl)thieno[3,2-c]pyridine (VIII) yielding adduct (IX), isolated as the dihydro-chloride salt. Finally, alkylation of the quinoline N atom of (IX) with bromoacetamide (A) under phase-transfer conditions furnished the title compound.

(I) The alkylation of 3-fluoroaniline (I) with 2-bromoacetamide (II) by means of KOH and Bu4NBr in THF gives 2-(3-fluorophenylamino)acetamide (III), which is condensed with 4-acetoxy-3,6-dihydro-2H-pyran-2,6-dione (IV) in Ac-OH to yield intermediate (V).

(I) Synthesis of intermediate (VII): Conversion of 3-fluoroaniline (I) into 2-amino-5-fluorobenzothiazole (III) can be achieved by first coupling with isocyanate (II) followed by hydrolysis with NaOH, reaction with Br2 and finally heating treatment. Dimerization of substituted benzothiazole (III) by means of refluxing aqueous KOH yields disulfide derivative (IV), which is then condensed with substituted benzoyl chloride (V) in refluxing pyridine to afford derivative (VI). Finally, (VI) is converted into intermediate (VII) by treatment with SnCl2 dihydrate in refluxing HCl/EtOH.
Alternatively, intermediate (VII) can be synthesized as follows: substituted aniline (VIII) is first brominated via a Sandmeyer reaction with NaNO2 in HBr and CuBr, and then the nitro group is reduced with SnCl2 in refluxing EtOH to provide derivative (IX). Condensation of (IX) with substituted benzoyl chloride (V) in refluxing pyridine yields amide (X), which is then first treated with Lawesson's reagent and HMPA and then with NaH in NMP to afford benzothiazole derivative (XI). Finally, the nitro group of (XI) is reduced with SnCl2 in refluxing EtOH to yield intermediate (VII).
Synthesis of EN 295753: The desired compound can finally be obtained by coupling of intermediate (VII) with Boc-Lys(Boc)-OH (XII) by means of carbodiimide WSC.HCl and HOBt in CH2Cl2, followed by Boc removal with HCl (gas) in CH2Cl2.

(I) Addition of thiocyanogen (generated in situ from KSCN and N-bromosuccinimide) to 3-fluoroaniline (I) gave the thiocyanoaniline (II). Subsequent acylation of aniline (II) with benzyl chloroformate afforded carbamate (III). The intermediate thiol produced by treatment of thiocyanate (III) with sodium sulfide was captured as the trityl sulfide (IV) upon quenching with bromotriphenylmethane. The chiral oxazolidinone (VI) was then obtained by condensation of the lithium salt of carbamate (IV) with (R)-glycidyl butyrate (V). Activation of the primary hydroxyl of (VI) as the corresponding mesylate (VII), followed by displacement with NaN3 in hot DMF gave rise to the alkyl azide (VIII). Removal of the S-trityl protecting group of (VIII) by means of trifluoroacetic acid and triisopropylsilane and further alkylation of the resultant thiol with iodomethane yielded the methyl sulfide (IX). Sulfoxide (X) was then obtained by oxidation of sulfide (IX) with m-chloroperbenzoic acid. Reduction of the azido group of (X) to the required amine (XI) was accomplished by treatment with triphenylphosphine followed by aqueous hydrolysis. Finally, condensation of amine (XI) with ethyl dithioacetate furnished the title thioacetamide.

The acylation of the NH2 group of (IV) with refluxing formic acid affords the formamide (V), which is cyclized by means of PPA and POCl3 in xylene at 100 C to provide the dibenzazepine (VI). The reduction of (VI) with H2 over Pd/C in THF/methanol gives the corresponding dihydro compound (VII), which is oxidized with 3-phenyl-2-(phenylsulfonyl)oxaziridine (VIII) in dichloromethane to yield the N-oxide (IX).

After conversion of alcohol (IV) to the corresponding mesylate, displacement with NaN3 provides azide (V). Reduction and acylation of (V) by means of thioacetic acid leads to acetamide (VI). Friedel-Crafts acylation of the aromatic ring of (VI) with acetic anhydride in the presence of methanesulfonic acid furnishes acetophenone (VII). Acidic hydrolysis of acetamide (VII) yields amine (VIII). This is then treated with thiophosgene, followed by methanol, to produce the thiocarbamate (IX). Finally, aldol condensation of the acetophenone (IX) with pyridine-2-carbaldehyde (X) gives rise to the target compound.
