실험 절차

To 4 mL of a methanol solution containing 0.14 g of 1-(2-(4-aminopiperidin-1-yl)ethyl)-7-methoxy-N-methyl-2-oxo-1,2-dihydroquinoline-4-carboxamide, 48 mg of 4-ethylbenzaldehyde and 40 μL of acetic acid were added, and stirred at room temperature for 80 min. To the reaction mixture, 52 mg of sodium cyanoborohydride was added, and stirred at the same temperature for 75 min. After the solvent was removed under reduced pressure, chloroform and aqueous saturated sodium hydrogen carbonate solution were added, the organic layer was separated, and the aqueous layer was extracted with chloroform. The organic layer and extracts were combined, washed with aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue thus obtained was purified by silica gel column chromatography [Silica Gel; Fuji Silysia Chemical Ltd., Chromatorex-NH, eluent; chloroform:methanol=30:1], to give 0.14 g of 1-(2-(4-(4-ethylbenzylamino)piperidin-1-yl)ethyl)-7-methoxy-N-methyl-2-oxo-1,2-dihydroquinoline-4-carboxamide as a pale yellow solid.
