Versuchsvorschrift

To 1.5 mL of dichloromethane solution containing 6.0 mg of 1-(2-(4-aminocyclohexyl)ethyl)-7-methoxy-4-methylquinolin-2(1H)-one, 10 mg of molecular sieves 3A, 3.4 mg of 2,3-dihydro(1,4)dioxino(2,3-c)pyridine-7-carbaldehyde and 1.6 μL of acetic acid were added at room temperature, and stirred at the same temperature for 1.5 hours. To the reaction mixture, 6.0 mg of sodium triacetoxyborohydride was added, and stirred at the same temperature for 1.5 hours. To the reaction mixture, aqueous saturated sodium hydrogen carbonate solution and chloroform were added. The organic layer was separated, 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[eluent; chloroform: methanol=10:1], to give 5.5 mg of 1-(2-(4-((2,3-dihydro(1,4)dioxino(2,3-c)pyridin-7-ylmethyl)amino)cyclohexyl)ethyl)-7-methoxy-4-methylquinolin-2(1H)-one as a yellow oil.
