Procedure

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.
