実験手順

1-((2R)-2-(N-((2E)-5-Amino-5-methylhex-2-enoyl)-N-methyl amino)-3-(2-naphthyl)propionyl-2-benzyl-4-ethylsemi-carbazide ##STR183## N'-Benzylidenehydrazinecarboxylic acid tert-butyl ester: ##STR184## To a solution of t-butyl carbazate (2.0 g, 15.1 mmol) in 99% ethanol (20 ml) was added benzaldehyde (1.6 g, 15.1 mmol) and the mixture was stirred for 30 min. Then the mixture was cooled to 0° C. and the precipitate was separated and washed with cold ethanol and dried in vacuo to give 2.7 g (81%) of N'-benzylidenehydrazinecarboxylic acid tert-butyl ester.
