Versuchsvorschrift

2.47 g of (5-trifluoromethyl-isoxazol-3-yl)methanol was dissolved in 80 ml of diethyl ether, and 6.56 g of triphenylphosphine and 8.9 g of carbon tetrabromide were then added. The mixture was stirred at room temperature for 1 hour. The reaction mixture was subjected to silica gel column chromatography to obtain 1.14 g of 3-(bromomethyl)-5-trifluoromethylisoxazole.
