Reaction Steps
10 g (60.2 mmol) of hydroxyphenylacetic acid methyl ester (Aldrich) is dissolved in 75 ml of acetone. 18.4 g (133 mmol) of solid potassium carbonate is added. 17.8 ml (123 mmol) of bromoacetic acid ethyl ester is added in drops under reflux within 15 minutes, it is kept at this temperature for another 4 hours, and it is stirred overnight at room temperature. Precipitate is filtered out, the solution is evaporated to the dry state and chromatographed on silica gel (hexane/ethyl acetate 3:1). The fractions that contain the product are combined and concentrated by evaporation.
