Procedure
3-Bromophenylacetic acid (5.03 g) was dissolved in ethanol (40 ml), conc. sulfuric acid (0.5 ml) was added, and the mixture was stirred overnight at room temperature. The reaction mixture was concentrated under reduced pressure. Water was added to the obtained residue, and the mixture was extracted with ethyl acetate. The organic layer was washed successively with water, saturated aqueous sodium hydrogencarbonate and brine, dried over sodium sulfate, and concentrated under reduced pressure to give the title compound (5.4 g).
