Procedure

To 490 mg (2.36 mM) of 6-m-fluorophenyl-1,3-oxazine-2,4-dione of Preparation IIa(1) is added 30.0 ml of a 40 percent aq. CH3NH2 solution. The reaction solution is heated at reflux for 18 hours. The solution is cooled and evaporated to dryness, under vacuum, to yield an amber solid. The solid is dissolved in CH3OH (hot), treated with darco, filtered and the CH3OH filtrate is evaporated to a white solid. The solid is recrystallized from H2O to yield 280 mg (54 percent) (m.p.: 192-194) of 1-N-methyl-6-m-fluorophenyl-2,4-pyrimidine-dione.
