0.11 g of N2 -[3(S)-(benzyloxyformamido)-2(R)-hydroxy-4-phenylbutyl]-N1 -tert.butyl-4(S)-hydroxy-L-prolinamide was dissolved in 10 ml of ethanol and hydrogenated over 20 mg of 10% palladium-on-carbon at room temperature and under atmospheric pressure for 2 hours. The catalyst was filtered off and the filtrate was evaporated to give 0.08 g of N2 -[3(S)-amino-2(R)-hydroxy-4-phenylbutyl]-N1 -tert.butyl-4(S)-hydroxy-L-prolinamide as a gum which was used without further purification.
