Participants

Reaction Steps

10 ml of ethyl acetate, 45 mg of oxalic acid and 10 ml of ethanol were added to 440 mg of ethyl({[7-(cyclohexylamino)-6-fluoro-4-oxo-1-(tetrahydrofuran-3-yl)-1,4-dihydroquinolin-3-yl]methyl}amino)acetate obtained by the same method of Example 4. After evaporation of the solvent under a reduced pressure and subsequent addition of ethyl acetate, the insoluble materials were collected by filtration to obtain 349 mg of ethyl({[7-(cyclohexylamino)-6-fluoro-4-oxo-1-(tetrahydrofuran-3-yl)-1,4-dihydroquinolin-3-yl]methyl}amino)acetate oxalate.
