実験手順
A solution of 181 mg of 1-[3(S)-[[N-(3-benzyloxy-2-naphthoyl)-L-asparaginyl]amino]-2(R)-hydroxy-4-phenylbutyl]-N-tert.butyl-2(S)-piperidinecarboxamide in 5 ml of ethanol washydrogenated 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. After trituration with diethyl ether there were obtained 110 mg of N-tert.butyl-1-[3(S)-[[N-(3-hydroxy-2-naphthoyl)-L-asparaginyl]amino]-2(R)-hydroxy-4-phenylbutyl]-2(S)-piperidinecarboxamide as a pale yellow solid: MS: m/e 632 [M+H]+.
