Methyl iodide → 4,6-Dimethyl-2-(methylsulfanyl)pyrimidine

Participants

Reaction Steps

4,6-Dimethyl-pyrimidine-2-thiol (20 g, 142 mmol) is added slowly to a solution of sodium hydroxide (6.3 g, 156 mmol) in ethanol (120 ml) and water (60 ml). Methyl iodide (9.8 ml, 156 mmol) is added dropwise and the mixture is stirred at room temperature for 1 hour. The solvents are removed in vacuo and the residue is partitioned between diethyl ether (200 ml) and water (200 ml). The organic extract is dried (MgSO4) and the solvent is removed to give the titled compound.
