Procedure

210 mg of the compound of Example 161 was suspended in 5.0 ml of DMF, to which 0.1 ml of ethoxycarbonylpiperazine, 130 mg of WSC.HCl and 100 mg of 1-hydroxybenzotriazole were added sequentially to the resulting reaction mixture under ice cooling, for stirring at ambient temperature for 17 hours. The reaction mixture was concentrated under reduced pressure, to which water was added for chloroform extraction. The resulting organic layer was washed sequentially with aqueous saturated NaHCO3 and aqueous saturated sodium chloride, dried over anhydrous sodium sulfate, filtered, concentrated under reduced pressure. The resulting solid was washed with EtOH, to obtain 228 mg of ethyl 4-[({[7-(cyclohexylamino)-1-ethyl-6-fluoro-4-oxo-1,4-dihydroquinolin-3-yl]carbonyl}amino)acetyl]piperazine-1-carboxylate.
