0.226 g of N2 -[3(S)-(benzyloxyformamido)-2(R)-hydroxy-4-phenylbutyl]-N1 -tert.butyl-4(R)-hydroxy-L-prolinamide was dissolved in 20 ml of ethanol and hydrogenated over 40 mg of 10% palladium-on-carbon at room temperatureand under atmospheric pressure for 2 hours. The catalyst was removed by filtration and the filtrate was evaporated to give 0.16 g of N2 -[3(S)-amino-2(R)-hydroxy-4-phenylbutyl]-N1 -tert.butyl-4(R)-hydroxy-L-prolinamide as a gum which was used without further purification.
