Procedure
Into 62 mL of 9% water-ethanol were suspended 5.00 g of (R)-1-(4-chlorophenyl)-3-(4-(2-methoxyethyl)piperazin-1-yl)methyl-2-pyrrolidinone and 3.30 g of maleic acid. After making it homogeneous by heating under reflux, the solution was cooled. The precipitated solid was filtered and dried to give 7.10 g of the title compound.
