Reaction Steps

To 557 mg of 3-(4-bromobutyl)-7-(cyclohexylamino)-1-(1-ethylpropyl)-6-fluoroquinolin-4(1H)-one was added 5 ml of triethylphosphite, followed by stirring at 160° C. for 4 hours. The reaction mixture was concentrated under a reduced pressure, and the resulting residue was purified by a column chromatography to obtain 240 mg of diethyl {4-[7-(cyclohexylamino)-1-(1-ethylpropyl)-6-fluoro-4-oxo-1,4-dihydroquinolin-3-yl]butyl}phosphonate.
