실험 절차

A solution of 5-amino-1-cyclopropyl-6,7-difluoro-1,4-dihydro-8-methoxy-4-oxo-2-phenylquinoline-3-carboxylic acid (550 mg, 1.42 mmol), N-2-pyridyl-1,2-ethanediamine (292 mg, 2.13 mmol) and triethylamine (0.297 mL, 2.13 mmol) in DMSO (7 mL) was stirred at 120° C. for 6 h. To the reaction mixture, water and NH4Cl was added to neutralize and the suspension was stirred for 30 min. The crude product was extracted with EtOAc, washed with brine, dried over MgSO4 and the solvent was removed in vacuo. The crude product was purified by column chromatography (Hexane:EtOAc 1:1→1:5) to yield 5-amino-1-cyclopropyl-6-fluoro-1,4-dihydro-8-methoxy-4-oxo-2-phenyl-7-[2-(2-pyridylamino)ethylamino]quinoline-3-carboxylic acid (356 mg, 50%) as a yellow solid.
