Procedure

4-Ethoxyaniline (40 g, 0.29 mol) and triethylamine (61 mL, 0.44 mol) were dissolved in dichloromethane (200 mL). Acetic anhydride (30 mL, 0.32 mol) was added in drops thereto, and the mixture was stirred for 1 h at 0° C. to room temperature. 1N hydrochloric acid solution was added, and the reaction mixture was extracted with ethyl acetate, washed with sodium chloride solution, and dried over anhydrous magnesium sulfate to give the title compound.
