실험 절차

Add K2CO2 (6.22 g, 45.1 mmol) and methyl iodide (24.6 g, 10.77 mL, 173.3 mmol) to 2-bromo-6-iodopyridin-3-ol, 2 (14.9 g, 49.5 mmol), dissolved in DMF (30 mL). Heat the reaction medium at 100° C. for 2 h, then leave it to cool to room temperature. Then stop the reaction with H2O and stir it for a further 30 min. The precipitate is then filtered, washed with H2O and dried in air to give 3 (15.7 g, 100%) in solid form, light brown: 1H NMR (CDCl3) δ 7.61 (d, 1H, J=8.4 Hz), 6.86 (d, 1H, J=8.4 Hz), 3.93 (s, 3H); m/z obs.=314 (M+1), 315.
