実験手順
6-methyl-2-sulfanylpyrimidin-4-ol (927 mg, 6.5 mmol) was dissolved in anhydrous DMF (30 mL), then potassium carbonate (2.70 g, 19.6 mmol) and 5-(bromomethyl)-1-ethyl-1H-pyrazole (8.5 mmol) in DMF (10 mL) 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/MeOH to afford 2-{[(1-ethyl-1H-pyrazol-5-yl)methyl]sulfanyl}-6-methylpyrimidin-4-ol (265 mg, 16% yield for 2 steps); 1H NMR (400 MHz, DMSO-d6): δ 1.32 (t, J=7.0 Hz, 3H), 2.21 (s, 3H), 4.15 (q, J=7.2 Hz, 2H), 4.50 (s, 2H), 6.04 (bs, 1H), 6.22 (d, J=1.7 Hz, 1H), 7.33 (d, J=1.7 Hz, 1H).
