Procedure
A solution of 4-bromophenylacetic acid (10.0 g, 46.5 mmol), in methanol (125 mL) and sulfuric acid (5 mL) was heated at reflux overnight. The reaction mixture was concentrated and partitioned between ethyl ether and saturated aqueous sodium bicarbonate. The organic layer was washed with water and brine, then dried over magnesium sulfate. The organic layer was filtered and evaporated to an oil to afford the title compound.
