Versuchsvorschrift

(A)(iii) A solution of 17 mg (0.04 mmol) of 2-[3(S)-azido-2(R)-hydroxy-4-phenylbutyl]--N-tert.butyl-decahydro-(4aS,8aS)-isoquinoline-3(S)-carboxamide (prepared as described in Example 2 or Example 3) in 5 ml of ethanol was hydrogenated at about 3.4 atmospheres and at room temperature for 2 hours over 10 mg of 10% palladium-on-charcoal. The catalyst was filtered off and washed twice with ethanol. The combined filtrate and washings were evaporated to give 16 mg of 2-[3(S)-amino-2(R)-hydroxy-4-phenylbutyl]-N-tert.butyl-decahydro-(4aS,8aS)-isoquinoline-3(S)-carboxamide; MS: m/e 402 [M+H]+.
