Reaction Steps
A solution of 1-(4-(trifluoromethoxy)phenyl)ethanol (150 mg; 0.72 mmol) in anh. DCM (5 ml) was treated at rt with CBr4 (241 mg; 0.72 mmol), and with PPh3 (190 mg; 0.72 mmol). The resulting mixture was further stirred at rt, under nitrogen, for 16 h. Concentration to dryness under reduced pressure, and subsequent purification by FC (DCM) afforded 1-(1-bromoethyl)-4-(trifluoromethoxy)benzene as a colorless oil which was directly used for the next reaction.
