Reaction Steps

After boiling 105.6 g of 4-methoxycarbonyl-2-nitrophenylhydrazine with 1 liter of glacial acetic acid for 1 hour, the clear orange-red solution was evaporated under reduced pressure. The residue was stirred with 1500 ml of water, the crystalline precipitate was filtered by suction, washed with water and dried at 80° C. to give 123 g (97%) of 4-methoxycarbonyl-2-nitro-N-acetylphenylhydrazine, in the form of yellow powder-like crystals, m.p.: 182°-185° C., which melted at 190°-192° C. after recrystallization from aqueous ethanol.
