Procedure

To a mixture of 5-(bromomethyl)-1-methyl-1H-1,2,3-benzotriazole (1.0 g, 4.22 mmol) and 6-methyl-2-sulfanylpyrimidin-4-ol (0.404 g, 2.87 mmol) in anhydrous ethanol (50 mL) at 0° C. was added triethylamine (0.894 g, 8.84 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-{[(1-methyl-1H-1,2,3-benzotriazol-5-yl)methyl]sulfanyl}pyrimidin-4-ol as a white solid (953 mg, 75% yield); 1H NMR (400 MHz, DMSO-d6): δ 2.21 (s, 3H), 4.28 (s, 2H), 4.55 (s, 3H), 6.04 (bs, 1H), 7.62 (d, J=8.7 Hz, 1H), 7.80 (d, J=8.7 Hz, 1H), 8.07 (s, 1H); M+287.5.
