Procedure
3-Bromo-4-methoxy-benzoic acid (2.5 g, 11.6 mmol) was dissolved in EtOH (20 mL) and conc. H2SO4 (1 mL) was added. The reaction was heated to reflux overnight then submitted to standard aqueous workup. The residue was purified by silica gel chromatography (0-50% EtOAc in hexanes) to yield the title compound.
