1-(2-Methoxyethyl)piperazine → 1-(4-Chlorophenyl)-3-(4-(2-methoxyethyl)piperazin-1-yl)methyl-2-pyrrolidinone

Participants

Reaction Steps

0.85 g of 1-(4-chlorophenyl)-3-methylene-2-pyrrolidinone and 0.71 g of 4-(2-methoxyethyl)piperazine were mixed with 3 ml of acetonitrile. The mixture was refluxed for 3.5 hours. The reaction mixture was concentrated to dryness. The residue was purified by silica gel column chromatography using a mixed solvent (chloroform/methanol=20/1) to obtain 1.1 g of 1-(4-chlorophenyl)-3-[4-(2-methoxyethyl)piperazine-1-yl]methyl-2-pyrrolidinone.
