실험 절차

To a stirred solution of (4-ethoxyphenyl)acetic acid (10.0 g, 55.5 mmol) in benzene (100 mL) was added thionyl chloride (50 mL, 68.5 mmol) and the reaction mixture was stirred at 80° C. for 2 hours. The solvent was evaporated in vacuo and the crude product was purified by distillation (bp 86° C., 0.4 Torr) to provide the title compound (10.39 g, 94%) as a yellow oil. MS of methyl ester: MS (ESI) (M+H)+=194.
