Procedure

To a solution of 7.0 g of 4-fluoro-3-[(3-fluorophenyl)-hydroxymethyl]-5-methoxybenzonitrile in 70 ml toluene was added 11.1 g of activated manganese dioxide at room temperature. After stirring at 60° C. for one day, the manganese dioxide was filtered off through Celite. The solvent was removed and the crude product was purified and separated by silica gel column chromatography (ethyl acetate:n-hexane=1:3), to give 640 mg of the title compound as colorless crystals.
