To a solution of methyl 4′-(methoxymethoxy)-2′,6′-dimethyl-6-(phenoxymethyl)biphenyl-3-carboxylate (1.77 g, 4.35 mmol) in a mixed solvent of methanol (10 mL) and dimethoxyethane (5 mL) was added 10% hydrogen chloride-methanol solution (1 mL), and the mixture was stirred at 45° C. for 16 hr. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate:hexane=10:90-25:75) to give the title compound (1.47 g, yield 93%) as a colorless amorphous powder.
