Versuchsvorschrift

A solution of 85% KOH (3.3 g, 50.7 mmol) and 5-methyl-2-thioxo-2,3-dihydro-1H-pyrimidin-4-one (7.2 g, 50.7 mmol) in absolute EtOH (100 ml) was stirred for 1 hour and then MeI (7.2 g, 50.7 mmol) was added dropwise. After refluxing the mixture for 2 hours, the solvent was removed under vacuum. The residue was triturated with water and the solid was filtered and dried in an oven to give 6.86 g of the title compound as a white powder (87% yield).
