4-(8-Nitroquinolin-4-yloxy)phenylamine (103 mL, 0.46 mmol), N-hydroxybenzotriazole (HOBt) (62 mg, 0.46 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarboimide (EDCl) (102 mg, 0.53 mmol) and 4-chloro-3-trifluoromethylbenzoic acid (103 mg, 0.46 mmol) were dissolved in dimethylformamide (3.6 mL), and to which triethylamine was added dropwise at room temperature, which was then heated and stirred at 80° C. When the reaction was completed, the resultant was extracted with ethyl acetate and saturated sodium bicarbonate, combined organic layers were dried with anhydrous sodium sulfate, and then filtered. The solvent was removed by vacuum distillation, and the residue was purified by a column chromatography (ethyl acetate/n-hexane=½) to obtain 125 mg of the desired compound as a brown solid (yield 71.2%).
