Reaction Steps

235 ml of acetic anhydride were added to a suspension of 97.5 g of 2-amino-4-carboxy-N-acetylphenylhydrazine in 450 ml of dichloromethane while stirring. The mixture was stirred at room temperature for 3 hours, then the crystals were filtered by suction, washed with dichloromethane and dried at 60° C. Thus, 101.2 g (86.5%) of 2-acetylamino-4-carboxy-N-acetylphenylhydrazine were obtained, m.p.: 238° C. (with decomposition).
