To the 2-(bromomethyl)-1-chloro-4-methoxybenzene (3.79 g, 16.09 mmol) in anhydrous ethanol (30 mL) at room temperature, 6-methyl-2-sulfanylpyrimidin-4-ol (2.28 g, 16.09 mmol) was added. Triethylamine (1.79 g, 17.7 mmol) was then added. The reaction mixture was stirred overnight at room temperature. The reaction progress was monitored by LCMS. The solvent was evaporated, and the crude residue was suspended in water and sonicated. The white precipitated product was filtered off and washed with water, ether, and ethyl acetate to provide the 2-{[(2-chloro-5-methoxyphenyl)methyl]sulfanyl}-6-methylpyrimidin-4-ol as a white solid (4.05 g, 85% yield); 1H NMR (400 MHz, DMSO-d6): δ 2.20 (s, 3H), 3.71 (s, 3H), 4.39 (s, 2H), 5.99 (bs, 1H), 6.88 (d, J=8.9 Hz, 1H), 7.19 (s, 1H), 7.38 (d, J=8.9 Hz, 1H).
