HCID 137083Acetamide, N-acetyl-N-phenyl-

Procedure

To a solution of N,N'-dimethyl-1,3-benzenediamine (27.2 g, 0.20 mol) in ethyl ether (300 ml) is added acetic anhydride (44.8 g, 0.44 mol) over 20 minutes at room temperature. The mixture is stirred at room temperature for 2 hours. The solution is diluted with ether (300 ml) and washed with saturated sodium carbonate solution and water, dried over magnesium sulfate, and concentrated to a solid. The solid is recrystallized from ethyl acetate-hexane to give the pure diacetanilide.
