실험 절차

To a solution of 1-(ethoxycarbonyl)-4-[[2-(3,4,5-trimethoxyphenyl)pyridin-4-yl]methylamino]piperidine (400 mg) in acetonitrile (5 mL) was added potassium carbonate (13 mg) and iodoethane (145 mg). The mixture was placed in sealed vessel and stirred at 80° C. for 2 hours. After removing the solvent in vacuo, ethyl acetate was added, washed with water and brine, dried over anhydrous sodium sulfate and evaporated. The residue was subjected to a column of silica gel using chloroform-methanol (30:1) as an eluent. Fractions containing the product were collected and evaporated to give the title compound as yellow syrup.
