Hydrazinecarboxaldehyde, 2-(4-nitrophenyl)- → Hydrazinecarboxaldehyde, 2-(4-aminophenyl)-

Participants

Reaction Steps

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