실험 절차

To 10 mL of a chloroform solution containing 226 mg of 1-(2-(4-aminopiperidin-1-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one and 150 mg of 2,2-difluorobenzo[1,3]dioxol-5-carbaldehyde, 43 μL of acetic acid was added, and stirred at room temperature for 1 hour. To the reaction mixture, 257 mg of sodium triacetoxyborohydride was added, and stirred for 2.5 hours. To the reaction mixture, aqueous saturated sodium hydrogen carbonate solution was added, 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=10:1] to give 188 mg of 1-(2-(4-((2,2-difluorobenzo[1,3]dioxol-5-yl)methylamino)piperidin-1-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one as a pale yellow solid.
