To a mixture of (4-cyclohexyl-3-trifluoromethyl-phenyl)-methanol (300 mg, 1.16 mmol) and PPh3 (460 mg, 1.74 mmol) in DCM (5 mL) at 0° C. is added CBr4 (580 mg, 1.74 mmol) dissolved in DCM (2 mL). The reaction is stirred at 0° C. for 1 h followed by concentration. The residue obtained is purified by silica gel chromatography (5% EtOAc in hexanes) to give 4-bromomethyl-1-cyclohexyl-2-trifluoromethyl-benzene as a white solid.
