Procedure
To a solution of 3-(3-hydroxy-2-methoxyphenyl)propanoic acid (50 mg) in methanol (10 mL) was added dropwise thionyl chloride (2.0 mL) at 0° C. The reaction mixture was heated under reflux for 3 hr. The reaction mixture was concentrated, and ethyl acetate was added. The reaction mixture was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give the title compound (45 mg) as a yellow oil. This compound was used for the next step without further purification.
