Reaction Steps

1.31 g of 1-(4-bromophenyl)-3-methylene-2-pyrrolidinone and 2.00 g of 4-(2-methoxyphenyl)piperazine were mixed with 5 ml of ethylene glycol dimethyl ether. The mixture was refluxed for 2 hours and then cooled. Thereto was added water. The mixture was subjected to extraction with ethyl acetate twice. The organic layer was dried over anhydrous magnesium sulfate and then concentrated to obtain an oily material. The oily material was purified by silica gel column chromatography using a mixed solvent of chloroform/methanol=40/1 to obtain 1.88 g of oily 1-(4-bromophenyl)-3-[4-(2-methoxyphenyl)piperazine-1-yl]methyl-2-pyrrolidinone.
