実験手順
3-Chlorophenol (0.52 g, 4 mmol), 4-fluorobenzaldehyde (0.50 g, 4 mmol), and potassium carbonate (0.56 g, 4 mmol) were stirred in DMF (5 mL) at 80° C. for 48 hours. The reaction mixture was diluted with ethyl acetate and washed with water and brine, dried over Na2SO4, filtered and evaporated to give the title compound in 95% yield. 1H NMR (CDCl3, 300 MHz) δ 6.95-7.40 (m, 9H), 7.85-8.31 (m, 4H), 9.94 (s, 1H). MS m/e 233 (M+H)+.
