Versuchsvorschrift

To a solution of 0.07 g of 1-(2-(4-aminopiperidin-1-yl)ethyl)-1,8-naphthyridin-2(1H)-one in 3 mL of dichloromethane, 57 mg of 7-chloro-3-oxo-3,4-dihydro-2H-pyrido(3,2-b)(1,4)thiazine-6-carbaldehyde and 14 μL of acetic acid were added, the mixture was stirred for 10 minutes, and then, 79 mg of sodium triacetoxyborohydride was added to the reaction mixture, and the mixture was reacted for 1 day. Thereto was further added 7 μL of acetic acid, the mixture was stirred for 35 minutes, and then, 7 μL of acetic acid and 26 mg of sodium triacetoxyborohydride was added thereto, and the mixture was reacted for 20 minutes. To the reaction mixture, water, a saturated aqueous sodium hydrogen carbonate solution, chloroform and sodium chloride were added, the organic layer was separated, and the aqueous layer was extracted with chloroform while salting out. The organic layer and the extract were combined, the resultant solution was dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The resultant residue was dissolved in 5 mL of 6 mol/L hydrochloric acid, and the solvent was distilled off under reduced pressure. The resultant residue was purified by reverse silica gel column chromatography using an eluent of water to obtain 71 mg of 7-chloro-6-(((1-(2-(2-oxo-1,8-naphthyridin-1(2H)-yl)ethyl)piperidin-4-yl)amino)methyl)-2H-pyrido(3,2-b)(1,4)thiazin-3(4H)-one hydrochloride as a light gray solid.
