Procedure

A stirred solution of (3-bromophenyl)acetic acid (10.0 g, 0.0465 mol) and concentrated sulfuric acid (4.5 mL) in MeOH (230 mL) was heated at 40° C. for 16 h. The reaction mixture was concentrated under reduced pressure and the residue was mixed with water (50 mL) and DCM (100 mL). The layers were separated and the organic layer was concentrated under reduced pressure. The residue was purified by silica gel flash chromatography (0-10% EtOAc/hexanes) to give the title compound (19.8 g, 91% yield) as a colorless oil.
