Procedure

6-methyl-2-sulfanylpyrimidin-4-ol (746 mg, 5.2 mmol) was dissolved in anhydrous DMF (30 mL), then potassium carbonate (2.18 g, 15.8 mmol) and 2-(bromomethyl)-1-(propan-2-yl)-1H-benzimidazole (1.99 g, 7.9 mmol) were added. The mixture was stirred overnight at room temperature. The solid was removed by filtration and washed with methanol, and the filtrate was evaporated. The residue was dissolved in DCM/MeOH and purified on silica gel using 12% DCM in MeOH to afford 6-methyl-2-({[1-(propane-2-yl)-1H-benzimidazol-2-yl]methyl}sulfanyl)pyrimidin-4-ol (1.01 g, 41% yield for 2 steps); 1H NMR (400 MHz, DMSO-d6): δ 1.55 (s, 3H), 1.56 (s, 3H), 2.20 (s, 3H), 4.76 (s, 2H), 4.84-4.92 (m, 1H), 6.06 (bs, 1H), 7.13-7.20 (m, 2H), 7.54-7.57 (m, HA 7.68-7.71 (m, 1H); LRMS (ES) m/z 315 (100%, M+1).
