Reaction Steps

4-(8-Nitroquinolin-4-yloxy)phenylamine (7.5 mg, 0.027 mmol) and 4-chloro-3-(trifluoromethyl)phenyl isocyanate (11.8 mg, 0.054 mmol) were dissolved in tetrahydrofuran, and stirred at room temperature for 12 hours. When the reaction was completed, the solvent was removed by vacuum distillation, and a white solid product was filtered to obtain 12.0 mg of the desired compound (yield 88.9%).
