実験手順

6-methyl-2-sulfanylpyrimidin-4-ol (200 mg, 1.4 mmol) was dissolved in absolute ethanol (15 mL), then triethylamine (230 μL, 1.7 mmol) and 1-(bromomethyl)-2-chloro-3-nitrobenzene (350 mg, 1.4 mmol) were added. The mixture was stirred overnight at room temperature. The solid was filtered, washed with methanol, and then dried in vacuo to afford 2-{[(2-chloro-3-nitrophenyl)methyl]sulfanyl}-6-methylpyrimidin-4-ol as white solid (277 mg, 64% yield); 1H NMR (400 MHz, DMSO-d6): δ 2.23 (s, 3H), 4.56 (s, 2H), 6.00 (bs, 1H), 7.56 (t, J=7.9 Hz, 1H), 7.95 (d, J=8.2 Hz, 2H); LRMS (ES+) m/z 312 (100%, M+1), 314 (45%, M+3).
