Potassium Carbonate → HCID 178429491, compound

Participants

Reaction Steps

6-methyl-2-sulfanylpyrimidin-4-ol (245 mg, 1.7 mmol) was dissolved in anhydrous DMF (10 mL), and then were added potassium carbonate (357 mg, 2.6 mmol) and 2-(bromomethyl)quinoxaline (500 mg, 2.2 mmol) in anhydrous DMF (5 mL). The mixture was stirred over a weekend at room temperature. The solvent was removed by evaporation, and the residue was dissolved in DCM and purified on silica gel using 10% DCM/MeOH to afford 6-methyl-2-[(quinoxalin-2-ylmethyl)sulfanyl]pyrimidin-4-ol (363 mg, 57% yield); 1H NMR (400 MHz, DMSO-d6): δ 2.17 (s, 3H), 4.72 (s, 2H), 6.01 (bs, 1H), 7.81-7.88 (m, 2H), 8.03-8.11 (m, 2H), 9.10 (s, 1H); LRMS (ES+) m/z 285 (100%, M+1).
