실험 절차

A solution of 3-(S)-t-butyloxycarbonylamino-1-t-butyloxycarbonylmethyl-5-acetoxy-2,3,4,5-tetrahydro-1H-[1]benzazepin-2-one (2.2 g) in ethanol (300 ml) containing 10% Pd/C (2.0 g) was placed in a pressure bottle and hydrogenated at 3 atmospheres pressure and 70° for 3 days. The catalyst was filtered off and the filtrate evaporated to give 3-(S)-t-butyloxycarbonylamino-1-t-butyloxycarbonylmethyl-2,3,4,5-tetrahydro-1H-[1]benzazepin-2-one, m.p. 164°-165° [α]D =-200.6° (c=0.64 in DMF).
