Ethyl iodoacetate → HCID 21250173, compound

Participants

Reaction Steps

16.8 g (0.075 mol) of 2-(4-chlorophenyl)-1-(pyrrolidin-1-yl)-ethanone are dissolved in 175 ml dimethylsulphoxide and after the addition of 8.9 g (0.08 mol) of potassium tert.butoxide, stirred for 15 minutes at ambient temperature. After the addition of 18.1 ml (0.085 mol) of ethyl iodoacetate the reaction mixture is stirred for 45 hours at ambient temperature. The solution is poured onto ice water and extracted with ethyl acetate. The combined organic extracts are washed with sodium chloride solution, dried and evaporated down. The residue is chromatographed on silica gel, eluting first with petroleum ether and later with petroleum ether/ethyl acetate (8:2 and 1:1). The desired fractions are combined and evaporated down.
