実験手順

To a 5.0 ml dichloromethane solution of 500 mg of 7-(cyclohexylamino)-1-(1-ethylpropyl)-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carbaldehyde were added 0.23 ml of diethyl phosphite and 0.22 ml of 1,8-diazabicyclo[5.4.0]-7-undecene at −40° C., followed by overnight stirring at room temperature. Aqueous saturated ammonium chloride was added to the reaction mixture, followed by extraction with chloroform and then washing with aqueous saturated sodium chloride. After drying over anhydrous sodium sulfate and subsequent evaporation under a reduced pressure, the resulting residue was purified by silica gel column chromatography to obtain 400 mg of diethyl[[7-(cyclohexylamino)-1-(1-ethylpropyl)-6-fluoro-4-oxo-1,4-dihydroquinolin-3-yl](hydroxy)methyl]phosphonate.
