실험 절차

1-bromo-2-methoxyethane (5.49 g, 39.5 mmol) was added to a mixture of 2-bromo-4-fluoro phenol (5 g, 26.18 mmol) and K2CO3 (11.5 g, 83.25 mmol) in CH3CN (41.5 mL) and continued stirring at 80° C. for 16 hr. The reaction mixture was quenched with 1M aq.NaOH solution, extracted with diethyl ether (3×100 mL), dried over anhydrous sodium sulphate and concentrated under reduced pressure to afford the crude, which was purified by column chromatography (using silica gel and 2% ethyl acetate in hexane as eluent) to afford the desired compound (Int-42). 1H NMR (300 MHz, CDCl3) δ ppm 7.3 (1H, m), 6.9 (1H, m), 6.7 (1H, m), 4.1 (2H, t), 3.8 (2H, t), 3.5 (3H, s).
