Reaction Steps

In 100 ml of acetonitrile were dissolved 15.3 g of p-nitrophenylhydrazine and 10.1 g of triethylamine, and 7.9 g of acetyl chloride was added dropwise to the solution under ice-cooling over a period of 15 minutes. Thereafter, the mixture was stirred for 1 hour at 25° C., 100 ml of water was added therreto, and crystals thus deposited were collected by filtration and washed with acetonitrile to provide 16.6 g of 1-acetyl-2-(4-nitrophenyl)hydrazine. The melting point was 209°-214° C.
