Reaction Steps

Thionyl chloride (2.41 ml) was added to a solution of (3-phenyl-5-isoxazolyl)methanol (2.89 g) in toluene (10 ml) and stirred at 60° C. for 1 hour. Water was added to the reaction mixture and extracted with ethyl acetate. The ethyl acetate layer was washed with an aqueous saturated solution of sodium chloride, dried (MgSO4) and concentrated. The remaining crystals were recrystallized from ethyl acetate-hexane to obtain 5-(chloromethyl)-3-phenylisoxazole (2.75 g, yield 86%) as pale-brown crystals. m.p. 69-70° C.
