2-Bromo-4-(trifluoromethyl)benzyl alcohol (4.0 g, 15.88 mmol) and Dess-Martin periodinane (7.14 g, 16.67 mmol) were combined in CH2Cl2 and stirred for 1.5 hours at room temperature. Saturated aqueous Na2CO3 was added, and a white precipitate was formed. The mixture was diluted with CH2Cl2 and saturated aqueous Na2CO3 and stirred for 1 hour. 1N Aqueous NaOH was added, and the organic layer was separated and concentrated. The residue was purified by silica gel chromatography (0-80% EtOAc in hexanes) to give the title compound.
