Procedure

To a mixture of 3-(bromomethyl)-7-methylimidazo[1,2-a]pyridine (1.0 g, 4.44 mmol), 6-methyl-2-sulfanylpyrimidin-4-ol (0.407 g, 2.88 mmol) in anhydrous ethanol (50 mL) at 0° C. was added triethylamine (0.898 g, 8.88 mmol). Then, the reaction mixture was allowed to stir at room temperature overnight. The solvent was evaporated to provide a crude residue. Ether was added to precipitate the triethylamine hydrochloride salt. The solid was filtered and washed with ether several times. The solvent was evaporated to provide a crude residue, which was purified by Combiflash using 0-10% methanol:dichloromethane to provide 6-methyl-2-[({6-methylimidazo[1,2-a]pyridin-3-yl}methyl)sulfanyl]pyrimidin-4-ol as a white solid (826 mg, 65% yield); 1H NMR (400 MHz, DMSO-d6): δ 2.25 (s, 3H), 2.31 (s, 3H), 4.79 (s, 2H), 6.04 (bs, 1H), 7.15 (d, J=8.0 Hz, 1H), 7.51 (d, J=8.0 Hz, 1H), 7.54 (s, 1H), 8.32 (s, 1H); M+286.5.
