Reaction Steps

(3-Methoxy-isoxazol-5-yl)-methanol (822 mg, 6.4 mmol) was dissolved in dichloromethane (10 ml) and triphenyl phosphine (1.84 g, 7.0 mmol) and carbon tetrabromide (2 g, 6.11 mmol) were added at 0° C. The mixture was stirred for 2 hours at 0° C. and concentrated. The crude product was purified by chromatography on silica gel (eluent: ethyl acetate/hexane) to give the product as a colourless oil (1.22 g, 99% yield) which was used in the next step without further purification.
