실험 절차

After dissolving 4-(1H-indol-5-yloxy)-6,7-dimethoxyquinoline (40 mg, 0.1249 mmol, described in WO9717329) in N,N-dimethylformamide (0.7 ml), sodium hydride (10 mg,) was added and the mixture was stirred at room temperature for 15 minutes. 2,4-Difluorophenyl isocyanate (0.018 ml, 0.1561 mmol) was further added, and the mixture was stirred at room temperature for 2 hours. Water was added to the reaction solution, extraction was performed with ethyl acetate, the extract was washed with saturated brine and dried over anhydrous magnesium sulfate, and the filtrate was distilled off under reduced pressure. The obtained crystals were suspended in diethyl ether:ethanol=10:1 and diluted with hexane, and then the crystals were filtered out, washed with diethyl ether:ethanol=10:1 and dried by aspiration to obtain the title compound (35 mg, 0.0736 mmol, 58.94%) as colorless crystals.
