Reaction Steps

N-(3-trifluoromethylphenyl)ethanolamine (4.17 g) and triphenyl phosphine (5.50 g) were dissolved in dry pyridine (35 ml) and stirred at 0° C. To this solution was added, portionwise, carbon tetrabromide (7.08 g). Stirring was continued for 1 hour and the reaction mixture was left to stand at room temperature overnight. A little more triphenyl phosphine (0.20 g) was added, and when virtually all starting alcohol had been consumed the pyridine was removed under reduced pressure to leave a brown residue (14.10 g). This was chromatographed on silica gel, eluting with ethyl acetate/hexane (1:9) as eluant to give the title compound as a light brown oil, yield 3.35 g.
