실험 절차

To a solution of 2-hydroxy-p-anisic acid (0.2 g, 1.2 mmol) in DCE (8 mL) was added thionyl chloride (0.13 mL, 1.8 mmol) and a drop of DMF. After stirring at room temperature for 4.5 h the reaction mixture was concentrated and azeotroped several times with benzene to give the acid chloride 123 as a white solid (222 mg).
