実験手順

To a solution of NaOH (7.46 g, 186.4 mmol) in water (120 mL), 4-methylpyrimidine-2-thiol hydrochloride (13.78 g, 84.7 mmol) was added and subsequently iodomethane (13.23 g, 93.2 mmol) was added dropwise under argon atmosphere. It was stirred at room temperature for 2 h. It was extracted with CH2Cl2 (×2). The organic phase was dried over Na2SO4 and concentrated to dryness. The crude product obtained was purified by chromatography on silica gel using hexane-EtOAc mixtures of increasing polarity as eluent, to afford 10.26 g of the desired compound (yield: 86%).
