Versuchsvorschrift

To 3-bromo-4-methoxyphenylacetic acid (24 g, 97.9 mmol) in ethanol (240 mL) was added thionyl chloride (7.8 mL, 107.7 mmol), and the reaction was stirred at room temperature for 1 hour. Once no starting material was seen by analytical LCMS, the mixture was basified with saturated aqueous NaHCO3 and extracted with dichloromethane. The combined organic layers were dried over MgSO4, filtered, and concentrated to give the desired product.
