実験手順

A mixture of 5-(chloromethyl)-1-ethyl-4-methyl-1H-imidazole hydrochloride (1.0 g, 5.1 mmol), 6-methyl-2-sulfanylpyrimidin-4-ol (500 mg, 3.5 mmol), and potassium carbonate (1.2 g, 9.0 mmol) in acetone (25 mL) was stirred at room temperature overnight. The solid material was removed by filtration. The filtrate was recovered and evaporated. The crude product was purified by flash chromatography (0-6% MeOH/DCM), affording 2-{[(1-ethyl-4-methyl-1H-imidazol-5-yl)methyl]sulfanyl}-6-methyl-pyrimidin-4-ol (428 mg, 46% yield); 1H NMR (400 MHz, DMSO-d6): δ 1.31 (t, 3H, J=6.7 Hz), 2.11 (s, 3H), 2.22 (s, 3H), 3.95 (m, 2H), 4.48 (s, 2H), 6.02 (s, 1H), 7.54 (s, 1H); M+ 266. The product was used without further purification.
