Reaction Steps

15.3 g of p-nitrophenylhydrazine and 10.1 g of triethylamine were dissolved in 100 ml of acetonitrile, and 7.9 g of acetyl chloride was added dropwise over 15 minutes with cooling with water. After conclusion of the addition, the mixture was stirred at 25° C. for 1 hour and thereafter 100 ml of water as added thereto. The precipitated crystals were filtered off, and washed with acetonitrile to obtain 16.6 g of 1-acetyl-2-(4-nitrophenyl)hydrazine. Yield: 16.6 g. Melting point: 209°-214° C.
