The resulting mixture was stirred for one hour at room temperature, then incorporated with 1.12 g of 5-bromo-6-chloro-3-methyl-4(3H)-pyrimidinone and stirred for 15 hours. The resulting solution was poured into water, and the resulting crystals were filtered off and then recrystallized from a benzene-hexane mixture to give 1.60 g of the intended product.
