Ethyl Acrylate → HCID 70157968, compound

Participants

Reaction Steps

3.46 g of t-butyl [(4-bromophenyl)thio]acetate was mixed with 8 ml diisopropylethylamine, 0.6 g of triphenylphosphine, 5.2 ml ethyl acrylate and 35 ml acetonitrile to form a solution. 0.26 g of palladium acetate was further added to the solution and refluxed under a stream of argon for 44 hours. The reaction mixture was extracted with ethyl acetate, washed with water. The aqueous layer was further extracted with ethyl acetate. The combined ethyl acetate layers were washed with water and brine, and then dried over anhydrous magnesium sulfate. The drying agent was filtered off and the filtrate was concentrated and purified via column chromatography on silica gel (ethyl acetate:hexane=1:20) to give ethyl 4-[[(t-butoxycarbonyl)methyl]thio]cinnamate (2.7 g, 73.7%).
