Versuchsvorschrift

A slurry of N′-ethylidene-hydrazinecarboxylic acid tert-butyl ester (5.0 g, 32 mmol), acetic acid (48 μL) and PtO2 (250 mg) in ethanol (50 mL) was shaken under a 40 psi pressure of H2 in a Parr hydrogenator for 24 h. The mixture was filtered through Celite to provide N′-ethylhydrazinecarboxylic acid tert-butyl ester (5 g) as a clear oil. MS (ESI+) for C7H16N2O2 m/z 161.0 (M+H)+.
