3) The condensation of 4-cyano-3(R)-hydroxybutyric acid ethyl ester (XXXV) with N,N-diphenylacetamide (R1 = R2 = Ph in XXVI) by means of LDA in THF gives 6-cyano-5(R)-hydroxy-3-oxo-N,N-diphenylhexanamide (XXVII), which is reduced with diethylmethoxyborane and NaBH4 in THF yielding 6-cyano-3(R),5(R)-dihydroxy-N,N-diphenylhexanamide (XXVIII). The protection of the two OH groups of (XXVIII) with acetone dimethylketal (XXIX) and methanesulfonic acid affords the 1,3-dioxane (XXX), which by reduction of its CN group by hydrogenation with H2 over RaNi in methanol/liquid ammonia gives intermediate (4R,6R)-2-[6-(2-aminoethyl)-2,2-dimethyl-1,3-dioxan-4-yl]-N,N-diphenylacetamide (XXXI). The cyclization of (XXXI) with 4-(4-fluorophenyl)-2-isobutyryl-4-oxo-N-phenylbutyramide (XXXII) (its synthesis is in section 6, Scheme 18007204a) in refluxing toluene yields the protected dihydroxyheptanamide (XXXIII), which is deprotected with HCl in methanol to afford (3R,5R)-7-[2-(4-fluorophenyl)-5-isopropyl-3-phenyl-4-(N-phenylcarbamoyl)pyrrol-1-yl]-3,5-dihydroxy-N,N-diphenylheptanamide (XXXIV). Finally, this compound is hydrolyzed with NaOH and treated with calcium acetate in water. 4) The preceding reaction pathway can be repeated using other substituents for R1 and R2 in acetamide (XXVI) such as R1 = R2 = CH2Ph; R1 = R2 = Et; R1 = Bu, R2 = Me; R1 = t-Bu, R2 = CH2Ph; R1,R2 = -(CH2)5-.
