Participants

Reaction Steps

3-Hydroxymethyl-5-phenyl-4,5-dihydroisoxazole (3.2 g) is dissolved in 50 ml of anhydrous ether. To the solution cooled with ice is slowly added dropwise 2.6 g of thionyl chloride with stirring. The reaction mixture is allowed to stand overnight at room temperature and then the solvent is distilled off to give 3-chloromethyl-5-phenyl-4,5-dihydroisoxazole in the form of yellow brown oil.
