Procedure

To a mixture of (4-(5-methyl-furan-2-ylmethyl)-phenyl)-methanol (350 mg, 1.7 mmol) obtained in Manufacturing Example 46-1-2 and dichloromethane (10 mL) was added manganese dioxide (3.5 g, 4.7 mmol) at room temperature, which was stirred overnight at room temperature. The reaction mixture was filtered through a Celite pad, and the filtrate was concentrated under a reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:heptane=1:6) to obtain the title compound (100 mg, 29%).
