Procedure

1-Benzoyl-2-(4-nitrophenyl)hydrazine (14.3 g, 0.056 mole) and 10% palladium/charcoal (catalytic amount) were suspended in ethanol (300 ml) in a Parr shaker bottle. The reaction mixture was hydrogenated at room temperature until hydrogen uptake ceased. The reaction mixture was filtered and the solvent was evaporated from the filtrate leaving a tan crystalline powder. Yield 11.5 g (90%), m.p. 134°-136° C.
