Synthesis
General procedure for the synthesis of 3-(bromomethyl)benzo[d]isoxazole from 2-(benzo[d]isoxazol-3-yl)-2-bromoacetic acid: 2-(benzo[d]isoxazol-3-yl)-2-bromoacetic acid (Ref. J. Med. Chem. 2003, 46, 5428-5436; Chem. Pharm. Bull. 1978, 26, 3498-3503) was slowly heated to 130 °C and stirred at this temperature for 30 min. A large amount of gas was observed to escape during the reaction. After completion of the reaction, the mixture was cooled to room temperature and filtered to obtain a brown crystalline product. Finally, the product was purified by column chromatography (eluent: hexane) to afford 3-(bromomethyl)benzo[d]isoxazole (2.3 g, 70% yield).
