Reaction Steps

46 g of 4-nitrophenylhydrazine was added to 160 ml of acetonitrile, and 32.2 g of formic acid was slowly added thereto at a temperature of 60° C. The reaction mixture immediately turned homogeneous and then crystals were again precipitated. The reaction was continued for an additional 2 hours at a temperature of 80° C., followed by cooling. The precipitated crystals were filtered, washed with acetonitrile and dried to obtain 49.5 g of 1-formyl-2-(4-nitrophenyl)hydrazine. Melting Point: 184°-186° C.
