Procedure
A solution of 5-(4-pyridylmethyl)-2-thiouracil (11.0 g), methyl iodide (7.2 g) and sodium hydroxide (2.1 g) in water (50 ml) and ethanol (100 ml) was stirred at 60° for 30 minutes, allowed to cool and filtered to give 5-(4-pyridylmethyl)-2-methylthio-4-pyrimidone m.p. 179°-182° (ethanol).
