실험 절차

Triphenyl phosphine (2.47 g, 9.8 mmol) and carbon tetrachloride (1.4 g, 9.1 mmol) were added to a THF solution (30 ml) of 5-fluoro-3-(4-methoxyphenyl)-4-oxo-8-propoxy-1,4-dihydro-quinoline-2-carboxy-(2-hydroxyethyl)amide (3.0 g, 7.24 mmol) and heated under reflux for 2 hours. The mixture was cooled to room temperature, and water was then added thereto, followed by extraction with dichloromethane. The thus-obtained organic layer was washed with water, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The residue was purified using silica gel column chromatography (dichloromethane:methanol=100:0→20:1). The purified material was concentrated to dryness under reduced pressure, giving a white powder of 5-fluoro-3-(4-methoxyphenyl)-4-oxo-8-propoxy-1,4-dihydroquinoline-2-carboxy-(2-chloroethyl)amide (1.8 g, yield: 58%).
