Procedure

2-{[(3,5-dichloropyridin-4-yl)methyl]sulfanyl}-6-methylpyrimidin-4-ol (200 mg, 662 μmol) was stirred in methanol (20 mL) and a solution of 4 N HCl in dioxane (250 μL, 993 mmol) was added dropwise at 0° C. The mixture was stirred for 30 minutes at room temperature (clear solution). The solvent was removed, and the residue was washed 3 times with diethyl ether and dried in vacuo to afford 2-{[(3,5-dichloropyridin-4-yl)methyl]sulfanyl}-6-methylpyrimidin-4-ol hydrochloride (164 mg, 73% yield); 1H NMR (400 MHz, DMSO-d6): δ 2.24 (s, 3H), 4.69 (s, 2H), 6.13 (s, 1H), 8.67 (s, 2H); LRMS (ES+) m/z 302 (100%, M+1), 304 (70%, M+3).
