実験手順

6-methyl-2-sulfanylpyrimidin-4-ol (686 mg, 4.8 mmol) was dissolved in anhydrous DMF (30 mL), and then potassium carbonate (2.0 g, 14.5 mmol) and 4-(bromomethyl)-3-ethylpyridine (5.8 mmol) in DMF (10 mL) were added. The mixture was stirred for 2.5 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 3-12% DCM/MeOH to afford 2-{[(3-ethylpyridin-4-yl)methyl]sulfanyl)-6-methylpyrimidin-4-ol (88 mg, 6% yield for 3 steps).
