Reaction Steps

The N-(4-piperidyl)-4-(N-acetyl-N-methylamino)benzenesulfonamide acetate (3.71 g, 10.6 mmol) prepared in Preparative Example 17 was dissolved in a suspension of sodium hydrogencarbonate (2.52 g) and potassium iodide (3.32 g) in dimethylformamide (50 ml), followed by the addition of 2-bromoethylbenzene (1.49 ml, 11.0 mmol). The obtained mixture was stirred at 70° C. for 3 hours, followed by the addition of water. The obtained mixture was extracted with ethyl acetate. The organic layer was washed with water and a saturated aqueous solution of common salt, dried over magnesium sulfate, and concentrated to give N-[1-(2-phenylethyl)-4-piperidyl]-4-(N-acetyl-N-methylamino)benzenesulfonamide as a colorless oil (3.19 g, yield: 77%).
