A mixture of 19.8 g of 1-amino-2-(4-methoxyphenyl)propane, 200 ml of ethyl acetate, 200 ml of water and 84 g of sodium bicarbonate is cooled at 5° to 10° C. under stirring, and 18.8 g of acetyl chloride in 100 ml of ethyl acetate are added dropwise thereto at the same temperature. After the reaction, the ethyl acetate layer is separated therefrom, washed, dried and then condensed to dryness under reduced pressure. 24.8 g of 1-acetylamino-2-(4-methoxyphenyl)propane are obtained as oil.
