To a solution of (2-benzyloxy-5-methoxyphenyl)-(4-methoxyphenyl)methanol (2.54 g, 7.25 mmol) in methanol (50 ml), a 20% palladium hydroxide catalyst (250 mg) was added and furthermore 36% HCl (0.25 mL) was added thereto. The mixture was stirred under a hydrogen atmosphere for 14 hours, and then the catalyst was filtered off. The solvent was distilled under reduced pressure, and the obtained residue was purified by silica gel column chromatography [developing solution=ethyl acetate:n-hexane (1:4)] to obtain the title compound (1.62 g, 91%).
