Reaction Steps

7-chloro-6-methoxy-3-(2-pyridyl)-1,2-benzisoxazole (24.4 g) is refluxed for 1.5 hours in 450 ml of 48% HBr. The precipitated hydrobromide salt is filtered off, washed with ether and neutralized with 10% NaHCO3 solution. The free base is filtered off and dried, giving 7-chloro-6-hydroxy-3-(2-pyridyl)-1,2-benzisoxazole, mp 209°-211° C.
