Procedure

To a solution of (3-benzyloxy-4-methylphenyl)methanol (1.0 g) in dichloromethane (50 mL) was added manganese dioxide (2.5 g), and this mixture was stirred at room temperature for 2 days. The insoluble material was removed by filtration and this filtrate was concentrated under reduced pressure. This residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate) to give the title compound (0.39 g)
