Versuchsvorschrift

A solution of 3-bromo-5-nitrobenzoic acid (15.4 g, 62.6 mmol) in methanol (120 mL) and sulfuric acid (1.7 mL, 31 mmol) was heated to reflux overnight. After cooling to 0° C. for 0.5 h, the precipitated solid was filtered to give the desired product as a white solid (15.5 g, 95%). LCMS for C8H7BrNO4 (M+H)+: m/z=260.0, 262.0.
