6-methyl-2-sulfanylpyrimidin-4-ol (152 mg, 1.1 mmol) was dissolved in absolute ethanol (20 mL), then triethylamine (200 μL, 1.4 mmol) and 4-(bromomethyl)-3-fluoropyridine (260 mg, 1.4 mmol) were added. The mixture was stirred over the weekend at room temperature. The solid was removed by filtration and washed with methanol. The filtrate was evaporated, and the residue was triturated in methanol, filtered, washed with water and diethyl ether, and then dried in vacuo to afford to 2-{[(3-fluoropyridin-4-yl)methyl]sulfanyl}-6-methylpyrimidin-4-ol (14 mg, 7% yield); 1H NMR (400 MHz, DMSO-d6): δ 2.18 (s, 3H), 4.41 (s, 2H), 6.00 (bs, 1H), 7.58 (t, J=5.7 Hz, 1H), 8.37 (dd, J=0.8 Hz, J=4.9 Hz, 1H), 8.53 (d, J=1.8 Hz, 1H); LRMS (ES+) m/z 252 (100%, M+1).
