Reaktionsschritte
Then, 30 g of 1-formyl-2-(4-nitrophenyl)hydrazine was catalytically reduced in 1.6 liters of ethanol at room temperature using palladium-carbon as a catalyst. The reaction mixture was filtered to remove the catalyst and the filtrate was evaporated to dryness to provide 20.5 g of 1-formyl-2-(4-aminophenyl)hydrazine having a melting point of 123°-125° C. as a light brown solid.
