Reaction Steps

750 mg (11.0 mmol) of imidazole and 2.88 g (11.0 mmol) of triphenylphosphine were added to a solution of 2.0 g (9.2 mmol) of 4-(3-(trifluoromethyl)phenyl)butan-2-ol in DCM (10 ml). 570 μl (11.0 mmol) of bromine were added dropwise at 0° C., and stirring was carried out for 1 h at RT. The mixture was then concentrated in vacuo. CC (hexane) of the residue yielded 2.0 g (7.1 mmol, 78%) of 1-(3-bromobutyl)-3-(trifluoromethyl)benzene.
