실험 절차
A solution of 1.25 g of 1-[3(S)-(benzyloxyformamido)-2(R)-hydroxy-4-phenylbutyl]-N-tert.butyl-2(S)-piperidinecarboxamide in 80 ml of ethanol was hydrogenated over 10% palladium-on-carbon at 20° C. and under atmospheric pressure for 16hours. The catalyst was removed by filtration and the filtrate was evaporated to give 0.844 g of 1-[3(S)-amino-2(R)-hydroxy-4-phenylbutyl]-N-tert.butyl-2(S)-piperidinecarboxamide as a pale yellow gum; MS: m/e 348 [M+H]+.
