실험 절차
4-(2-Aminoethyl)morpholine (184 mg, 1.41 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (WSC, 295 mg, 1.54 mmol) and 1-hydroxybenzotriazole (HOBT, 215 mg, 1.41 mmol) were added to a DMF solution (7 ml) of [5-fluoro-3-(4-hydroxyphenyl)-4-oxo-8-propoxy-4H-quinolin-1-yl]acetic acid (500 mg, 1.34 mmol) and then the mixture was stirred at room temperature for 23 hours. Water and triethylamine were added to the reaction mixture to make the reaction mixture basic, followed by extraction using ethyl acetate. The thus-obtained organic layer was washed with an aqueous saturated sodium chloride solution, and then concentrated under reduced pressure. The residue was purified using silica gel column chromatography (dichloromethane:methanol=30:1→10:1). The purified product was concentrated under reduced pressure, and the residue was recrystallized from ethyl acetate, giving a white powder of 2-[5-fluoro-3-(4-hydroxyphenyl)-4-oxo-8-propoxy-4H-quinolin-1-yl]-N-(2-morpholin-4-ylethyl)acetamide (157 mg, yield: 24%).
