Procedure

14.4 g (72 mmol) of (3-bromo-4-methylphenyl)methanol are placed in 200 ml of dichloromethane in a round-bottomed flask. 62.6 g (72 mmol) of manganese oxide are added and the medium is stirred at room temperature overnight. The mixture is filtered through Celite and the solvent is evaporated off. 11.8 g (85%) of the expected product are obtained in the form of an oil.
