Procedure
200 mg of diethyl {(E)-2-[7-(cyclohexylamino)-1-(1-ethylpropyl)-6-fluoro-4-oxo-1,4-dihydroquinolin-3-yl]vinyl}phosphonate was dissolved in 2.0 ml of chloroform, and 0.4 ml of bromotrimethylsilane was added, followed by overnight stirring at room temperature. Ethanol was added to the reaction mixture, followed by concentration under a reduced pressure. Ethyl acetate was added to the resulting residue, and the insoluble materials were collected by filtration to obtain 120 mg of {(E)-2-[7-(cyclohexylamino)-1-(1-ethylpropyl)-6-fluoro-4-oxo-1,4-dihydroquinolin-3-yl]vinyl}phosphonic acid hydrobromide.
