3-Bromophenol (500 mg, 2.86 mmol) and pyridin-3-ylboronic acid (422 mg, 3.76 mmol) were dissolved in dimethoxyethane/water=5 mL/2.5 mL. Pd(dppf)Cl2 (118 mg, 0.14 mmol) and sodium carbonate (919 mg, 8.67 mmol) were added thereto, followed by stirring in microwave at 120° C. for 20 minutes. After the completion of the reaction, the reaction mixture was filtered using Celite. The filtrate was added with water, and extracted with ethyl acetate. The obtained organic layer was dried over magnesium sulfate, and purified by column chromatography (hexane:ethyl acetate=9:1) to obtain 3-(pyridin-3-yl)phenol (386 mg, 78%).
