Aqueous 5 N sodium hydroxide solution (44 mL) was added to a THF (150 mL)-MeOH (150 mL) solution of methyl 2,6-dimethoxybiphenyl-4-carboxylate (20.0 g), and stirred at 40° C. for 5 hours. The reaction solution was poured into aqueous 0.5 M KHSO4 solution, and extracted with ethyl acetate. The combined organic layers were washed with aqueous saturated sodium chloride solution, dried with anhydrous sodium sulfate, and concentrated. The residue was recrystallized from hexane/ethyl acetate to obtain the title compound as a colorless crystal.
