Reaction Steps

To a solution of 2.47 g (11.1 mmol) of crude 2-methyl-5-phenylbenzylisocyanate in 50 ml of tetrahydrofuran was added 0.82 g of acetohydrazide and the mixture was heated under reflux for 1 hour. After allowing to cool to room temperature, the reaction mixture was concentrated, and the residue was recrystallized from ethanol to obtain 0.93 g (3.13 mmol) of 1-acetyl-4-(2-methyl-5-phenylbenzyl)semicarbazide.
