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 2-(furan-2-yl)-4-methoxyphenol (212 mg, 57%).
