Participants

Reaction Steps

In a 150-ml ground-necked flask equipped with a reflux condenser, 5 g (0.02 mol) of 3-methyl-6-( 3-chloropropionyl)benzoxazolinone, described in Patent Application FR 89/02554, are dissolved in 70 ml of dimethylformamide. 2.04 g of potassium acetate are introduced. The mixture is heated with magnetic stirring to 75°-80° C. for 50 min. After cooling, the reaction mixture is poured into ice-cold water. The resulting mixture is stirred for 0.5 h. The precipitate obtained is drained, washed with water, dried and recrystallized in toluene.
