2-bromo-4-fluoro-6-methylphenol (337 mg, 1.20 mmol), 3-furanylboronic acid (162 mg, 1.45 mmol), Pd(dppf)Cl2 (98.3 mg, 0.12 mmol) and sodium carbonate (383 mg, 3.61 mmol) were dissolved in DME:water=20 mL:10 mL, followed by stirring in microwave at 120° C. for 20 minutes. The reaction mixture was filtered through Celite. The filtrate was concentrated under reduced pressure, and purified by column chromatography (silica gel; hexane/ethyl acetate, 9/1) to obtain 4-fluoro-2-(furan-3-yl)-6-methylphenol (96 mg, 30%) as a yellow oil.
