Procedure

A mixture of 5-(bromomethyl)-4-ethyl-1,3-thiazole (7.0 mmol), 6-methyl-2-sulfanylpyrimidin-4-ol (700 mg, 4.9 mmol), and triethylamine (3.0 mL, 21.5 mmol) in absolute ethanol (70 mL) was stirred at room temperature overnight. The mixture was evaporated, and the residue was treated with 50% diethyl ether/acetone (100 mL). The solid material was removed by filtration. The filtrate was recovered and evaporated. The crude product was purified by flash chromatography (0-10% MeOH/CH2Cl2). The column was repeated 4 times, affording the title compound (132 mg, 10% yield); 1H NMR (500 MHz, DMSO-d6): δ 1.19 (t, 2H, J=7.5 Hz), 2.801 (m, 2H, J=7.5 Hz), 4.55 (s, 2H), 6.05 (s, 1H), 8.85 (s, 1H); M+268.
