A solution of 43 g (200 mmol) of 4-bromophenylacetic acid and 0.2 g of conc. H2SO4 in 470 ml of ethanol was refluxed for 16 hours. The reaction mixture was cooled to ambient temperature, stirred with 6 g of solid K2CO3 for 30 minutes and then filtered. The filtrate was concentrated in vacuo, diluted with Et2O (200 ml), washed with 10% aqueous NaHCO3 (10 ml) and brine (10 ml), dried over MgSO4 and concentrated in vacuo to give the title compound as a colorless oil.
