Procedure

A mixture of 1-(bromomethyl)-2-chloro-4-methoxybenzene (1.0 g, 4.2 mmol), 6-methyl-2-sulfanylpyrimidin-4-ol (550 mg, 3.9 mmol), and triethylamine (585 μL, 4.2 mmol) in absolute ethanol (20 mL) was stirred at room temperature overnight. The product was recovered by filtration, washed with water (2×20 mL) and diethyl ether (2×20 mL), and dried in vacuo, affording the title compound (929 mg, 81% yield); 1H NMR (400 MHz, DMSO-d6): δ 2.07 (s, 3H), 3.76 (s, 3H), 4.41 (s, 2H), 6.00 (s (br), 1H), 6.89 (dd, 1H, J=2.5 Hz, 8.6 Hz), 7.07 (d, 1H, J=8.6 Hz), 7.52 (d, 1H, J=8.6 Hz); M+297.
