실험 절차

274 mg of N2 -[3(S)-[[N-[4-(benzyloxycarbonyl)benzoyl]-L-asparaginyl]amino]-2(R)-hydroxy-4-phenylbutyl]-N1 -tert.butyl-L-prolinamide in 100 ml of isopropanol were hydrogenated over 10% palladium-on-carbon at 20° C. and under atmospheric pressure for 16 hours. The catalyst was removed by filtration and the filtrate was evaporated to give 193 mg of N2 -[3(S)-[[N-(4-carboxybenzoyl)-L-asparaginyl]amino]-2(R)-hydroxy-4-phenylbutyl]-N1 -tert.butyl-L-prolinamide as a white solid from methanol/ethyl acetate; MS: m/e 596 [M+H]+.
