30 g of 1-formyl-2-(4-nitrophenyl)hydrazine was then catalytically reduced at room temperature in 1.6 l of ethanol using palladium-carbon as a catalyst. The reacting solution was filtered, and the filtrate was evaporated to dryness to obtain 20.5 g of 1-formyl-2-(4-aminophenyl)hydrazine as light brown solid. Melting Point: 123° to 125° C.
