实验过程

A dichloromethane solution (6 ml) of 1-(3-aminopropyl)-5-fluoro-3-(4-methoxyphenyl)-8-propoxy-1H-quinolin-4-one (645 mg, 1.67 mmol) was ice-cooled. Triethylamine (253 mg, 2.5 mmol) and chloroacetyl chloride (207 mg, 1.83 mmol) were added to the solution and stirred at room temperature for 2 hours. Water was added to the reaction mixture, followed by extraction using dichloromethane. The thus-obtained organic layer was condensed, and the residue was then purified using silica gel column chromatography (dichloromethane:ethyl acetate=4:1→2:1). The purified product was concentrated to dryness under reduced pressure, giving a white powder of 2-chloro-N-{3-[5-fluoro-3-(4-methoxyphenyl)-4-oxo-8-propoxy-4H-quinolin-1-yl]propyl}acetamide (372 mg, yield: 48%).
