実験手順
Gemifloxacin free base (3 gm) is added to methylene dichloride (65 ml) at 25-30 ° C., ethanol (20 ml) is added to form a clear solution. To the solution, formic acid (0.4ml) is added at 25-l 30° C., stirred for 1 hour and then cooled to 10° C. Filtered the solid and dried at 50- 55° C. to give 2.6 gm of gemifloxacin formate (HPLC Purity: 99.93%).
