Potassium Carbonate → HCID 69484304, compound

Participants

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 4-bromobutyric acid ethyl ester is added in drops under reflux within 15 minutes, and it is kept at this temperature for another 4 hours and stirred overnight at room temperature. Precipitate is filtered out, the solution is evaporated to the dry state, and it is chromatographed on silica gel (hexane/ethyl acetate 3:1). The fractions that contain the product are combined and concentrated by evaporation.
