In 30 ml of dichloromethane was suspended 6.0 g (69.0 mmol) of active manganese dioxide. Next, 1.17 g (3.45 mmol) of 4-[2-[4-(dibutylamino)phenyl]vinyl]benzyl alcohol was dissolved in dichloromethane and added to the suspension. After stirred at room temperature for 20 hours, the suspension was filtrated and the solvent was evaporated off. The residue was purified by silica gel column, chromatography to give 0.74 g of a yellow crystal (yield: 64.1%).
