Procedure

Benzoxalinone (202 g) and N-methylethanolamine (133 g) were stirred and heated at 75° C. for 3 hours, then cooled to 65° C. and methanol (50 ml) was added. The mixture was cooled to ambient temperature and diethyl ether (750 ml) was added. The precipitate was filtered off and recrystallised from methanol to give the desired urea which had a m.pt. of 128° C. (decomp.).
