Reaction Steps

A mixture of 1-chloro-3-[2-oxopyrrolidin-1-yl]propane (1 g, 6.2 mmcl), 1-(3-chlorophenyl)piperazine (1.22 g, 6.2 minol) anhydrous Na2CO3 (0.33 g, 3.1 mmol) and Nal (0.093 g, 0.6 mmcl) in dry xylene (15 ml) was stirred at 150° C. for 14 hours. The solvent was removed at reduced pressure and residue was poured on water (30 ml). The separated residue was extracted with dichloromethane (2×25 ml), dried over Na2SO4 and concentrated to give 1-[4-(3-chlorophenyl)piperazin-1-yl]-3-[3-oxopyrrolidin-1-yl]propane as an oil which was purified by flash column chromatography over silica gel using chloroform as fluent, yield 0.72 g (36%).
