Versuchsvorschrift

To 10 mL of a chloroform solution containing 139 mg of 1-(2-(4-aminopiperidin-1-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one and 69 mg of 2,3-dihydro-1,4-dioxino[2,3-b]pyridine-7-carbaldehyde, 28 mg of acetic acid was added, and stirred at room temperature for 1 hour. To the reaction mixture, 133 mg of sodium triacetoxyborohydride was added, and stirred overnight. To the reaction mixture, aqueous saturated sodium hydrogen carbonate solution was added, and 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 N, eluent; chloroform:methanol=10:1] to give 162 mg of 1-(2-(4-((2,3-dihydro-1,4-dioxino[2,3-b]pyridin-7-yl)methylamino)piperidin-1-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one as a white solid.
