Reaktionsschritte

1-Formyl-2-(4-nitrophenyl)hydrazine (10.2 g, 0.056 mole) and 10% palladium/charcoal (catalytic amount) were suspended in ethanol (500 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 white crystalline powder. Yield 7.1 g (84%), m.p. 122°-125° C.
