Procedure
A solution of 101 mg of conc. sulfuric acid in 5 mL of ethanol was added to a solution of 352 mg of (R)-1-(4-chlorophenyl)-3-(4-(2-methoxyethyl)piperazin-1-yl)methyl-2-pyrrolidinone in 10 mL of ethanol. The mixture was stirred at room temperature and then concentrated to 3 mL. To the mixture was added 5 mL of ethyl acetate. The precipitated solid was filtered and dried to give 389 mg of the title compound.
