Reaktionsschritte

To a solution of 2-(3,5-dimethoxyphenyl)acetic acid (5) (600 mg, 3.06 mmol) in MeOH (30 mL) was added dropwise thionyl chloride (3 mL) at 0° C., and the reaction mixture was stirred at room temperature overnight. The reaction was monitored by liquid chromatography-mass spectrometry (LCMS). The mixture was diluted with saturated sodium bicarbonate (aq., 20 mL) and extracted by EtOAc (3×20 mL). The combined organic layers were washed with water and brine, dried over sodium sulfate, filtered and concentrated to give methyl 2-(3,5-dimethoxyphenyl)acetate (crude, 700 mg) as a yellow oil. MS (ES+) C11H14O4 requires: 210. Found: 211 [M+H]+.
