실험 절차

213 μl of diisopropyl azodicarboxylate was added to a 5.0 ml dichloromethane solution of 263 mg of benzyl (2R)-2-hydroxy-3-phenylpropanoate and 270 mg of triphenylphosphine at 0° C., followed by stirring for 15 minutes. Then, 177 mg of 7-(cyclohexylamino)-1-cyclopentyl-6-fluoro-3-(hydroxymethyl)quinolin-4(1H)-one was added thereto, followed by stirring at room temperature for 4 hours. Water was added to the reaction mixture, followed by extraction with EtOAc and washing with aqueous saturated sodium chloride. After drying over anhydrous sodium sulfate and subsequent evaporation under a reduced pressure, the residue was purified by silica gel column chromatography to obtain 160 mg of benzyl (2S)-2-{[7-(cyclohexylamino)-1-cyclopentyl-6-fluoro-4-oxo-1,4-dihydroquinolin-3-yl]oxy}-3-phenylpropanoate.
