실험 절차

Compound 6 (2.00 g) was dissolved in pyridine (50 mL), and 1-chlorocarbonyl-4-piperidinopiperidine (2.50 g) was added to the solution, followed by stirring under reflux for 2 hours. After completion of reaction, methanol was added to the reaction mixture, followed by stirring for 30 minutes. The solvent was evaporated under reduced pressure, and the residue was extracted with chloroform and purified water. The organic layer was dried over sodium sulfate anhydrate, and the solvent was evaporated to dryness. The residue was recrystallized from ethyl acetate, to thereby yield the target product (yield: 974 mg, 30%).
