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

Participants

Reaction Steps

In 1,600 ml of ethanol, 30 g of 2-(4-nitrophenyl)-1-formylhydrazine was catalytically reduced at room temperature, using palladium-carbon as a catalyst. The reaction mixture was filtered and the filtrate was evaporated to dryness, whereby 20.5 g of white solid 2-(4-aminophenyl)-1-formylhydrazine was obtained. Melting point: 123° to 125° C.
