Potassium Carbonate → HCID 178429540, compound

Participants

Reaction Steps

6-methyl-2-sulfanylpyrimidin-4-ol (1.2 g, 8.8 mmol) was dissolved in anhydrous DMF (50 mL), then potassium carbonate (3.6 g, 26.3 mmol) and 1-(bromomethyl)-3,5-dimethyl-1H-pyrazole (3.0 g, 15.8 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 10% DCM in MeOH to afford 2-{[(3,5-dimethyl-1H-pyrazol-1-yl)methyl]sulfanyl)-6-methylpyrimidin-4-ol (218 mg, 10% yield for 2 steps); 1H NMR (400 MHz, DMSO-d6) δ 2.12 (s, 3H), 2.22 (s, 3H), 2.30 (s, 3H), 5.81 (s, 2H), 5.83 (s, 6.07 (bs, 1H); LRMS (ES+) m/z 251 (50%, M+1).
