Versuchsvorschrift

To 10 mL of a chloroform solution containing 404 mg of 1-(2-(4-aminopiperidin-1-yl)ethyl)-7-fluoroquinoxalin-2(1H)-one and 180 mg of phenylpropargylaldehyde, 80 μL of acetic acid were added, and stirred at room temperature for 1 hour. To the reaction mixture, 474 mg of sodium triacetoxyborohydride was added, and stirred overnight. 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; Fuji Silysia Chemical Ltd., Chromatorex-NH, eluent; ethyl acetate:hexane=2:1], to give 224 mg of 7-fluoro-1-(2-(4-(3-phenyl-2-propyn-1-ylamino)piperidin-1-yl)ethyl)quinoxalin-2(1H)-one as brown solid and 158 mg of 1-(2-(4-(bis(3-phenyl-2-propyn-1-yl)amino)piperidin-1-yl)ethyl)-7-fluoroquinoxalin-2(1H)-one as yellow oil.
