2-Aminobenzophenone (I) is acylated with bromoacetyl bromide followed by reaction with ammonia to form the [1,4]benzodiazepine. N1-Methylation produces 1,3-dihydro-1-methyl-5-phenyl-2H-[1,4]benzodiazepin-2-one (II). Treatment with isoamyl nitrate and t-BuOK gives an oxime, which is reduced by catalytic hydrogenation to racemic 3-amino-benzodiazepine (III), which is isolated as the crystalline benzenesulfonic acid salt. Crystallization-induced asymmetric transformation yields 3(S)-(-)-3-amino-1,3-dihydro-1-methyl-5-phenyl-2H-[1,4]benzodiazepin-2-one (IV). Acylation with indole-2-carbonylimidazolide produces MK-329.

Several novel syntheses of 2-butyl-5-chloro-3H-imidazole-4-carbaldehyde (XI), a key intermediate in the synthesis of losartan, have been described: 1) Treatment of glycine methyl ester hydrochloride (I) with NaOH in methanol, followed by reaction with methyl pentanimidate (II), gives 2-butyl-4,5-dihydro-1H-imidazol-5-one (III), which is treated with POCl3 to give the 2-butyl-5-chloro-1H-imidazole (IV). Reaction of (IV) with POCl3 and DMF yields the enamine (V), which is finally hydrolyzed with water to 2-butyl-5-chloro-3H-imidazole-4-carbaldehyde (XI), the desired intemediate in the synthesis of losartan. 2) Imidazolinone (III) can also be obtained by cyclization of chloroacetic acid methyl ester (VI), chloroacetyl chloride (VII) or bromoacetyl bromide (VIII) with pentanamidine (IX) by means of NaOH in methanol. 3) Alternatively, imidazolinone (III) can be treated with dimethylformamide dimethylacetal in dichloromethane yielding the enamine (X), which is finally treated with POCl3 and hydrolyzed with water. 4) The reaction of glycine (XI) with methyl pentanimidate (II) in NaOH/MeOH gives amidine (XII), which, without isolation, is treated with POCl3 and DMF at 100 C for 2 h, and then hydrolyzed with water to give the desired 2-butyl-5-chloro-3H-imidazole-4-carbaldehyde. Methyl pentanimidate (II) is obtained treating a solution of valeronitrile in MeOH with HCl gas followed by neutralization with aqueous KOH and extraction with Et2O.

The cyclization of (VIII) in refluxing pyridine gives the tricyclic ethyl ester (IX), which by reaction with P2S5 in refluxing pyridine is converted into the corresponding thioketone (X). The reaction of (X) with hydrazine in methanol yields the 2-hydrazino derivative (XI), which is acylated with acetyl chloride (XII) and NaHCO3 in THF affording the 2-(acetylhydrazino) derivative (XIII). The cyclization of (XIII) in refluxing acetic acid gives the tetracyclic ethyl ester (XIV), which is decarboxylated with 30% HBr yielding the tetracyclic precursor (XV). The acylation of (XV) with 2-(3,4-dimethoxyphenylthio)acetic acid (XVI) by means of dicyclohexylcarbodiimide (DCC) in DMF affords the acylated compound (XVII), which is finally treated with P2S5 or Lawesson's reagent.

2) An improved procedure consisted of condensation of 5-nitroisatoic anhydride (I) with beta-alanine ethyl ester (V) to give amide (XIV). The amino group of (XIV) was protected with benzhydryl bromide (VII) yielding (XV), and then the nitro group of (XV) was reduced to aniline (XVI) by catalytic transfer hydrogenation. Protection of the amine of (XVI) as the tert-butyl carbamate (XVIII) was effected using 2-(tert-butoxycarbonyloxymino)-2-phenylacetonitrile (XVII). The sequence of condensation of (XVIII) with bromoacetyl bromide (IX), followed by cyclization of the intermediate bromoacetamide with DBU provided the benzodiazepinedione (XIX). Hydrogenolysis of the N-benzhydryl group of (XIX) in the presence of Pearlman's catalyst, followed by treatment with trimethylsilyl azide furnished the tetrazole (XX). The Boc group of (XX) was deprotected with trifluoroacetic acid, and subsequent coupling with 4-cyanobenzoyl chloride (III) gave amide (XXI). The cyano group was of (XXI) then converted to hydroxyamidine (XXII) with hydroxylamine. Catalytic hydrogenation of (XXII) in the presence of Ac2O and AcOH produced the corresponding amidine. Finally, the ester group was hydrolyzed with LiOH.

The esterification of (XIX) with bromoacetyl bromide (XX) and dimethylaniline (DMA) affords the corresponding ester (XXI), which is oxidized with O3 and trimethyl phosphite and cyclized with SmI2 in THF to provide the chiral tetrahydropyranone (XXII). The reduction of (XXII) with Red-Al, followed by cyclization with 2-methoxypropene (XXIII) and PPTS, gives the acetonide (XXIV), which is oxidized with PPTS and NMO to provide the protected dihydroxyketone (XXV). The condensation of the ketone (XXV) with 2(S)-methyl-6-heptenal (XXVI) by means of LDA in THF gives the hydroxyundecenone (XXVII), which is treated with pyridinium p-toluenesulfonate (PPTS) in methanol to cleave the 1,3-dioxane ring and yield the trihydroxy compound (XXVIII). The silylation of (XXVIII) with Tbdms-OTf and lutidine in dichloromethane affords the fully silylated compound (XXIX), which is selectively monodesilylated with CSA to provide the primary alcohol (XXX). Finally, this alcohol is oxidized by means of pyridinium dichromate (PDC) in DMF to furnish the target tridecenoic acid intermediate (XII).

Lithiationof 5-fluoro-2-methoxybenzoic acid (I) with sec-BuLi in the presence of TMEDA in THF, followed by methylation of the resulting anion with methyliodide, gives 3-fluoro-6-methoxy-2-methylben methyl benzoic acid (II). Chlorination of carboxylic acid (II) with (COCl)2 in the presence of DMF in CH2Cl2 and subsequent reaction of the resulting acid chloride with PhOH by means of Et3N and DMAP in CH2Cl2 provides the corresponding phenyl ester (III). O-Demethylation of ether (III) by means of BBr3 in CH2Cl2 at −78° Cyields the 6-hydroxybenzoate (IV),which is then protected with Boc2O and DMAP in CH2Cl2 to generate the tert-butyl carbonate (V). Treatment of compound (V) with LDA and TMEDA in THF at −78°C, followed by coupling with enone (VI) in THF, produces the tetraceno[2,3-d] isoxazole derivative (VII),which is subsequently deprotected with HF and TFA in acetonitrile to give the octa hydrotetracene derivative (VIII). Reductive cleavage of the isoxazolering of tetracycline (VIII) with H2 over Pd/Cin methanol/dioxane affords the 2-hydroxyamide (IX),which by nitration with HNO3 and H2SO4 affords the 9-nitro-tetracycline derivative (X). Reduction of the nitro group of compound(X) with H2 over Pd/Cin methanol/dioxane gives the corresponding amine(XI).Then, reaction of amine (XI) with bromoacetyl bromide(XII) in the presence of Na2CO3 in DMPU/acetonitrile provides the bromoacetamide(XIII), which is finally condensed with pyrrolidine(XIV). Alternatively,amine(XI) is directly condensed withp yrrolidin-1-ylacetyl chloride(XV) orits hydrochloride salt in DMF.

Reaction of bromoacetyl bromide (I) with phenol at 80 °C gives the phenyl ester (II) , which by cyclization with (S)-(+)-phenylglycinol (III), previously treated with DIEA, in acetonitrile provides 5(S)-phenylmorpholin-2-one (IV) . Treatment of compound (IV) with HCl affords the corresponding HCl salt (V), which is reacted with NaHCO3 followed by coupling with benzodioxane-6-carboxaldehyde (VI) in refluxing EtOAc/toluene to yield the oxazine adduct (VII). Oxazine derivative (VII) can also be obtained by direct coupling of 5(S)-phenylmorpholin-2-one (IV) with aldehyde (VI) in refluxing toluene. Opening of adduct (VII) with pyrrolidine (VIII) in CH2Cl2, CHCl3 or refluxing THF followed by addition of HCl in refluxing MeOH leads to 3-(1,4-benzodioxan-6-yl)-3(R)-hydroxy-2(R)-(2-hydroxy-1-phenylethylamino)-1-(pyrrolidin-1-yl)propanone (IX), which is reduced with LiAlH4 in refluxing THF to give diol (X). Cleavage of diol (X) by means of H2 and Pd(OH)2 in the presence of either CF3COOH or HCl in MeOH or EtOH/H2O provides amine (XI), which is finally coupled with octanoic acid N-hydroxysuccinimide ester (XII) in CH2Cl2 . Ester (XII) is prepared by condensation of octanoyl chloride (XIII) with N-hydroxysuccinimide (XIV) by means of Et3N in CH2Cl2 .
