Participants

Reaction Steps

2-sulfanyl-6-(trifluoromethyl)pyrimidin-4-ol (1.56 g, 8.0 mmol) was dissolved in anhydrous DMF (50 mL), and then potassium carbonate (3.3 g, 23.9 mmol) and 4-(bromomethyl)-3-ethylpyridine (10.3 mmol) in DMF (10 mL) were added. The reaction 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 3-12% DCM/MeOH to afford 2-{[(3-ethylpyridin-4-yl)methyl]sulfanyl}-6-(trifluoromethyl)pyrimidin-4-ol (357 mg, 14% yield for 3 steps); 1H NMR (500 MHz, DMSO-d6): δ 1.21 (t, J=7.5 Hz, 3H), 2.75 (q, J=7.5 Hz, 2H), 4.46 (s, 2H), 6.65 (s, 1H), 7.41 (d, J=5.1 Hz, 1H), 8.34 (d, J=5.0 Hz, 1H), 8.42 (s, 1H); LRMS (ES+) m/z 316 (100%, M+1).
