Procedure
41.3 g of 4-nitrophenylhydrazine and 33 g of phthalide were dissolved in 330 ml of acetonitrile. The solution was heated under reflux with stirring over 4 hours. The reaction solution was allowed to stand for cooling to room temperature. The resulting solid was then filtered off, and recrystallized from acetonitrile to obtain 15.1 g of 1-(2'-hydroxymethylbenzoyl)-2-(4-nitrophenyl)hydrazine (yield of 21.0%).
