Cyclopropylamine → N-{4-[6-(Cyclopropylamino)carbonyl-7-methoxy-4-quinolyl]oxyphenyl}-N'-(4-fluorophenyl)urea

Participants

Reaction Steps

After dissolving the N-[4-(6-carboxy-7-methoxy-4-quinolyl)oxyphenyl]-N′-(4-fluorophenyl)urea (60 mg) synthesized in Example 341 in dimethylformamide (1.5 ml), there were added 1-ethyl-3-(3-diethylaminopropyl)-carbodiimide hydrochloride (39 mg), 1-hydroxy-1H-benzotriazole monohydrate (31 mg), triethylamine (30 μl) and cyclopropylamine (0.05 ml) and the mixture was stirred overnight at room temperature. The reaction solution was distributed between ethyl acetate and water, and the organic layer was washed with water and then dried over anhydrous sodium sulfate. After distilling off the solvent, crystals were precipitated with ethyl acetate, filtered out and dried under reduced pressure to obtain the title compound (29 mg) as white crystals.
