실험 절차

4-Amino-1-benzylpiperidine (3.63 ml, 17.8 mmol) was added to a suspension of the 4-(N-acetyl-N-methylamino)benzenesulfonyl chloride (4.00 g, 16.2 mmol) prepared in Preparative Example 12 and sodium acetate (2.65 g) in ethanol (40 ml). The obtained mixture was stirred at room temperature for 4 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-benzyl-4-piperidyl)-4-(N-acetyl-N-methylamino)benzenesulfonamide as a colorless viscous oil. This oil was dissolved in 4N aqueous hydrochloric acid and the obtained solution was heated under reflux for 3 hours. The resulting mixture was concentrated to give a solid residue. This residue was recrystallized from ethyl acetate to give the title compound as a white crystal (highly hygroscopic one) (5.80 g, overall yield of two steps: 80%).
