Participants

Reaction Steps

6-methyl-2-sulfanylpyrimidin-4-ol (846 mg, 5.9 mmol) was dissolved in anhydrous DMF (40 mL), then potassium carbonate (2.46 g, 17.8 mmol) and 5-(bromomethyl)-1-methyl-1H-imidazole (1.56 g, 8.9 mmol) were added. The mixture was stirred for 4 hours at room temperature. The solid was removed by filtration, washed with methanol, and the filtrate was evaporated. The residue was dissolved in DCM/MeOH and purified on silica gel using 10% DCM in MeOH to afford 6-methyl-2-{[(1-methyl-1H-imidazol-5-yl)methyl]sulfanyl}pyrimidin-4-ol (589 mg, 42% yield for 2 steps); 1H NMR (400 MHz, DMSO-d6): δ 2.22 (s, 3H), 3.61 (s, 314), 4.44 (s, 2H), 6.02 (s, 1H), 6.88 (s, 1H), 7.56 (s, 1H); LRMS (ES+) m/z 237 (100%, M+1).
