실험 절차

55 ml of a 1N K2CO3 solution are added dropwise to 3.12 g (5.5 mmol) of 1-[4-(thiazol-2-yl)-phenyl]-4(S)-hydroxy-2-(tert-butoxycarbonyl)amino-5(S)-(trifluoroacetyl)amino-6-phenyl-2-azahexane in 55 ml of methanol and the mixture is stirred at 70° C. for 9 hours. The mixture is cooled and ≈30 ml of methanol are evaporated off; methylene chloride and water are added and the aqueous phase is separated off and extracted with methylene chloride; the organic phases are washed with water, dried (Na2SO4) and concentrated by evaporation, yielding the title compound: HPLC20-100: tRet=1.9; FAB MS (M+H)+=469.
