Reaction Conditions

Reaction Steps

A solution of (3-methylisoxazol-5-yl)methyl benzoate (20.1 g, 92.4 mmol) in acetic acid (77.3 mL) was treated with N-bromosuccinimide (19.7 g, 111 mmol) and heated in a sealed tube at 90° C. for 4 h. The reaction mixture was diluted with brine and extracted with ethyl acetate. The organic layer was separated, washed with brine, dried over magnesium sulfate, filtered, and concentrated to give the crude product. Purification by flash column chromatography (100% hexanes to 20% ethyl acetate/hexanes) gave the desired product (21.6 g, 79%). LCMS calculated for C12H11BrNO3 (M+H)+: m/z=296.0, 298.0. found: 296.0, 298.0.
