Procedure

9 g of 3-acetamido-5-methylaniline are dissolved in 20 ml of dimethylformamide and 3.2 ml of 3-bromobutan-2-one are then added. The mixture is left at ambient temperature for 1 hour and the temperature is then raised to 100°-110° C. for one hour. The mixture is cooled and poured into 100 ml of ice-water. The precipitate is drained and washed successively with 50 ml of distilled water, 20 ml of ethanol and 20 ml of isopropyl ether. 4.2 g of white precipitate are obtained.
