Reaction Steps

10 g of 5,7-dichloro-3-(2-fluorophenyl)-6-methoxy-1,2-benzisoxazole is combined with 100 g pyridine hydrochloride and heated at 200° C. for 0.5 hours. The hot melt is quickly poured into stirred ice water and a resultant precipitate is filtered and dried for 48 hours in vacuo (64° C.). The solid is recrystallized from toluene affording 5,7-dichloro-3-(2-fluorophenyl)-6-hydroxy-1,2-benzisoxazole, mp 194°-196° C.
