実験手順

To a solution of (2-benzyloxyphenyl)-p-tolylmethanol (1.5 g, 4.43 mmol) in methanol (27 mL), a 20% palladium hydroxide catalyst (150 mg) was added and furthermore 2N—HCl (0.37 mL) was added thereto. The mixture was stirred under a hydrogen atmosphere for 24 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 (1:10)] to obtain the title compound (617 mg, 70%).
