Reaction Steps
A solution of (4-methoxy-2-trifluoromethyl-phenyl)-methanol (1.04 g, 5 mmol) in DCM (20 mL) was treated at 0° C. with phosphorous tribromide (1.64 g, 6 mmol). The reaction mixture was stirred for 10 minutes at 0° C., 1 h at room temperature. The solvent was evaporated in vacuo to yield a crude oil which was purified via flash chromatography (10% DCM in hexane) to yield the title compound as an oil (1.36 g, 100%).
