Reaction Conditions

Reaction Steps

To a stirred suspension of {5-[3-(trifluoromethyl)phenyl]isoxazol-3-yl}methane-1-ol (0.28 g, 1.15 mmol) and carbon tetrabromide (0.5 g, 1.5 mmol) in methylene chloride (10 mL) at 0° C. was added dropwise a solution of triphenylphosphine (0.41 g, 1.58 mmol) in methylene chloride (5 mL). The resulting mixture was stirred at 0° C. for 1 hour, then the reaction mixture poured into ethyl acetate and Hexanes (ethyl acetate:Hexanes=1:4, 50 mL). The resulting suspension was filtered through a thin layer of silica gel and washed with ethyl acetate and Hexanes (ethyl acetate:Hexanes=1:4). The filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate:Hexanes=1:4) to afford 3-(bromomethyl)-5-[3-(trifluoromethyl)phenyl]isoxazole.
