实验过程
A solution of 4.6 g of 1-[3(S)-(benzyloxyformamido)-2(R)-hydroxy-4-phenylbutyl]-N-tert.butyl-octahydro-cyclopenta[b]pyrrole-2-carboxamide (four diastereomers) in 90 ml of ethanol was hydrogenated over 10% palladium-on-carbon at 20° C. and under atmospheric pressure for 72 hours. The catalyst was removed by filtration and the filtrate was evaporated to give 2.958 g of 1-[3(S)-amino-2(R)-hydroxy-4-phenylbutyl]-N-tert.butyl-octahydro-cyclopenta[b]pyrrole-2-carboxamide (four diastereomers) as a brownish oil; MS: m/e 374 [M+H]+.
