Procedure

28 ml of a 1N K2CO3 solution are added dropwise, at 70° C., to 1.9 g (2.8 mmol) of 1-{4-[2-(1-methyl-1-phenyl-ethyl)-2H-tetrazol-5-yl]-phenyl}-4(S)-hydroxy-2-(tert-butoxycarbonyl)amino-5(S)-(trifluoroacetyl)amino-6-phenyl-2-azahexane in 29 ml of methanol and the mixture is stirred for 15 hours. After cooling and concentration by evaporation, methylene chloride and water and added; the aqueous phase is separated off and extracted with methylene chloride. The organic phases are washed with water, dried (Na2SO4) and concentrated by evaporation to yield the title compound: HPLC20-100 : tRet =15.1; FAB MS (M+H)+ =469.
