2-Methoxyethylamine → 6-(2-Methoxyethylcarbamoyl)-7-methoxy-4-(indol-5-yloxy) quinoline

Participants

Reaction Steps

After dissolving 6-carboxy-7-methoxy-4-(indol-5-yloxy)quinoline (100 mg) in dimethylformamide (4.0 ml), there were added methoxyethylamine (0.04 ml), triethylamine (0.08 ml) and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (198 mg), and the mixture was stirred at room temperature for 5 hours. Water was added to the reaction solution, extraction was performed with ethyl acetate, and then the organic layer was washed with water and saturated brine in that order and dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. Ethyl acetate was used for recrystallization to obtain the title compound (86 mg).
