Participants

Reaction Steps

3 ml of ethyl acetate and 0.35 ml of a 1 M hydrogen chloride ethyl acetate solution were added to 0.13 g of ethyl({[7-(cyclohexylamino)-1-ethyl-6-fluoro-4-oxo-1,4-dihydroquinolin-3-yl]methyl}amino)acetate obtained by the same method of Example 9. After evaporation of the solvent under a reduced pressure and subsequent addition of ether, the insoluble materials were collected by filtration to obtain 97 mg of ethyl({[7-(cyclohexylamino)-1-ethyl-6-fluoro-4-oxo-1,4-dihydroquinolin-3-yl]methyl}amino)acetate hydrochloride.
