To a solution of (2,6-dichloro-3-fluorophenyl)methanol (9.0 g, 46 mmol) in dichloromethane (200 mL) was added molecular sieves (4A, powder, 40g) and pyridinium dichromate (PDC: 45g, 120 mmol). The mixture was stirred at room temperature for 2 h and diluted with Et2O (200 mL). The mixture was filtered through Celite and the solvent was removed in vacuum. The residue was washed with a small amount of dichloromethane to give a white solid (4.6 g, yield 52%).
