To a solution of 1-(3-methylisoxazol-5-yl)propan-1-ol (0.589 g, 4.17 mmol) in 15 mL of THF was added CBr4 (1.730 g, 5.22 mmol) and triphenylphosphine (1.423 g, 5.42 mmol). The reaction mixture was stirred at room temperature for 3 h. The solid was filtered off, and washed with THF. The filtrate was concentrated and residue was purified by chromatography on silica gel, eluting with 5 to 30% EtOAc/hexane to provide the title compound. Mass Spectrum (ESI) m/z=204.2 (M+1).
