Procedure

To a resealable vial was added (3-methylisoxazol-5-yl)methyl benzoate (907 mg, 4.18 mmol), AcOH (3.5 ml, 61.1 mmol), and NBS (892 mg, 5.01 mmol). The reaction was heated to 110° C. overnight. The reaction was cooled to room temperature and diluted with water. The aqueous was extracted with EtOAc and the combined organics were washed with brine, dried over Na2SO4, filtered, and concentrated. The crude residue was purified via Biotage (EtOAc/hex) to afford (4-bromo-3-methylisoxazol-5-yl)methyl benzoate. m/z (ESI) 296, 298 [M+H]+.
