Reaction Steps

5-Bromo-3-phenyl-2,1-benzisoxazole (7.5 g, 28.6 m mol), water (14.6 ml), and zinc dust (9.3 g, 143 m mol) were combined. Acetic acid (8.6 ml, 143 m mol) was added and the mixture was stirred and heated at 80° C. for 90 minutes. After cooling to room temperature, both the liquid and solid portion of the reaction were extracted with methylene chloride. The combined methylene chloride solutions was washed once with sodium hydroxide solution (10%) and several times with water. Drying (sodium sulfate) and evaporation yielded the desired product (7.42 g) of mp. 92°-102° C.
