Procedure
5 g of 3-bromophenylacetic acid are dissolved in 80 ml of ethanol, 3 ml of concentrated H2SO4 are added and then the mixture is heated at reflux for two hours. The ethanol is evaporated, neutralization is carried out with a saturated K2CO3 solution and then extraction is carried out with AcOEt. The organic phase is dried over MgSO4. 5.2 g of the expected compound are obtained in the liquid form.
