실험 절차
4-(2-Fluoro-4-methoxyphenyl)-2-methoxypyridine (1.34 g, 5.72 mmol) was stirred in concentrated hydrochloric acid (25.5 mL) at reflux for 18 h. The reaction was cooled to 0° C. and neutralized with solid NaOH. The resulting solids were collected by filtration and dried under vacuum to yield the title compound (1.09 g, 87%) as a light brown solid: 1H NMR (300 MHz, DMSO-d6) δ 7.52-7.38 (m, 2H), 6.97-6.85 (m, 2H), 6.42-6.33 (m, 2H), 3.80 (s, 3H); ESI MS m/z 220 [M+H]+.
