Reaction Steps
250 mg of 3-amino-7-(cyclohexylamino)-1-cyclopentyl-6-fluoroquinoline-4(1H)-one and 127 mg of 4-ethoxy-4-oxobutanoic acid were dissolved in 20 ml of DMF, and 170 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride and 160 mg of 1-hydroxybenzotriazole were added, followed by overnight stirring at room temperature. By adding water to the reaction mixture and collecting the insoluble materials by filtration, 220 mg of ethyl 4-{[7-(cyclohexylamino)-1-cyclopentyl-6-fluoro-4-oxo-1,4-dihydroquinolin-3-yl]amino}-4-oxobutanoate was obtained.
