Ethyl 2,3-dibromopropionate is used as pharmaceutical Intermediates. It is a building block that has been used as a catalyst for the polymerization of ethyl acrylate. | [Synthesis]
General method: A solution of 1.2 moles of carbon tetrachloride (CCl4) with bromine (Br2) was slowly added dropwise to a stirred solution of carbon tetrachloride (CCl4) containing 1 mole of ethyl acrylate at 0°C. The reaction mixture was allowed to run for 2 hours. After the dropwise addition was completed, the reaction mixture was warmed to 60 °C and refluxed for 2 hours. The progress of the reaction was monitored by thin layer chromatography (TLC) and after the reaction was complete, the solvent was evaporated under reduced pressure to give ethyl 2,3-dibromopropionate in 99% yield. | [References]
