Procedure
Benzoxazolinone (1 mole) was stirred with 2 moles of diethylamine (dissolved in industrial alcohol) at 50° C. for 48 hours, then the alcohol and excess of diethylamine were distilled off under reduced pressure at below 60° C. The residue was taken up in acetone, the desired product was precipitated by adding water and then it was filtered off and dried under reduced pressure at 80° C.
