反应详情

To 3-bromo-4-methoxyphenylacetic acid (24 g, 97.9 mmol) in EtOH (240 mL) was added thionyl chloride (7.8 mL, 107.7 mmol), and the reaction was stirred for 35 minutes. Once no starting material was seen by analytical LCMS, the mixture was quenched with NaHCO3 until the solution was basic, and then extracted twice with CH2Cl2. The combined organic layers were dried over MgSO4, filtered, and concentrated to give the title compound.
