실험 절차

To 20 mL of a chloroform solution containing 176 mg of 1-(2-(4-aminopiperidin-1-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one and 102 mg of 2-oxo-1,2,3,4-tetrahydroquinoline-7-carbaldehyde, 34 μL of acetic acid was added, and stirred at room temperature for 1 hour. To the reaction mixture, 200 mg of sodium triacetoxyborohydride was added, and stirred for 2.5 hours. Aqueous saturated sodium hydrogen carbonate solution was added, the organic layer was separated. The organic layer was 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; Kanto Chemical Co., Inc., Silica Gel 60, eluent; chloroform:methanol=100:1] to give 178 mg of 7-methoxy-1-(2-(4-((2-oxo-1,2,3,4-tetrahydroquinolin-7-ylmethyl)amino)piperidin-1-yl)ethyl)quinoxalin-2(1H)-one as a pale brown foam.
