Reaction Steps

To 2-thioxo-2,3-dihydropyrimidin-4(1H)-one (21 g) was added dropwise a solution of sodium hydroxide (13 g) in water (120 mL), iodomethane (11.5 mL) was added thereto, and the mixture was stirred overnight at room temperature. To the reaction mixture was added acetic acid (9.5 mL), and the resulting solid was collected by filtration. The obtained solid was washed with cold water to give the title compound (24 g).
