Versuchsvorschrift
A mixture of 6-(3-benzyloxy-propyl)-2-mercapto-pyrimidin-4-ol (7.94 g), potassium hydroxide (32 mL of 1N solution in methanol) and methyl iodide (1.97 mL) was stirred at room temperature overnight. The precipitate was filtered, washed successively with methanol (2×20 mL), isopropanol (2×20 mL) and water (2×20 mL), then dried to afford 6-(3-benzyloxy-propyl)-2-methylsulfanyl-pyrimidin-4-ol as a white powder (7.0 g). MS m/z 291.0 (M+1), 100%.
