该中间体在本合成路线中的序号:(I)

The reaction of 3-bromomethyl-1,2-benzisoxazole (I) with sodium sulfite in hot methanol - water gives sodium 1,2-benzisoxazole-3-methanesulfonate (II), which by reaction with refluxing POCl3 is converted into 1,2-benzisoxazole-3-methanesufonyl chloride (III). Finally, this compound is treated with dry NH3 in ethyl acetate.
