실험 절차

6-methyl-2-sulfanylpyrimidin-4-ol (491 mg, 3.4 mmol) was dissolved in anhydrous DMF (25 mL), then potassium carbonate (1.43 g, 10.3 mmol) and 4-(bromomethyl)-1,3-thiazole (922 mg, 5.2 mmol) were added. The mixture was stirred for 4 hours 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 to 6-methyl-2-[(1,3-thiazol-4-ylmethyl)sulfanyl]pyrimidin-4-ol (268 mg, 32% yield for 2 steps); 1H NMR (400 MHz, DMSO-d6): δ 2.21 (s, 3H), 4.53 (s, 2H), 6.00 (bs, 1H), 7.63 (d, J=2.0 Hz, 1H), 9.06 (d, J=2.0 Hz, 1H).
