実験手順: To a solution of tert-butyl carbazate (1.0 g, 7.6 mmol) and pyridine (3.1 ml) in methylene chloride (5 ml) was slowly added acetic acid anhydride (1.5 ml) and the mixture was stirred overnight. The mixture was added to methylene chloride (50 ml) and washed with water (2×10 ml) and brine (10 ml) and dried (MgSO4), filtered and concentrated in vacuo to give 0.95 g of N'-acetylhydrazinecarboxylic acid tert-butyl ester as a yellow oil. washed with water (2×10 ml) and brine (10 ml) dried (MgSO4) filtered concentrated in vacuo
