The resulting 1-(3,3-diphenylpropyl)homopiperazine was dissolved in 3 mL of ethanol, mixed with 228 mg of 2-(chloromethyl)quinoline hydrochloride and 141 mg of potassium carbonate, and stirred at 70° C. for 14 hours. The mixture was cooled to room temperature and the ethanol was removed under reduced pressure, 20 mL of aqueous 2N sodium hydroxide was added and the mixture was extracted with 20 mL×2 of ethyl acetate. The organic layers were combined, washed with 20 mL of saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, filtered, concentrated, and purified by column chromatography (silica gel, ethyl acetate/methanol 95:5), to obtain 109 mg of the titled compound. This was treated with a hydrogen chloride solution in ether and the solvent was removed under reduced pressure and the residue was dried to give the hydrochloride salt of the titled compound.
