反応手順
1 g of levofloxacin crude was put in suspension in 7 ml of n-BuOH. The mixture was heated to reflux temperature until complete dissolution of the material. Then the solution was cooled to RT over a period of 2.5 hours. The precipitate was filtrated under vacuum, washed with n-BuOH and dried at 60° C. in a vacuum oven to give 810 mg (81%) of purified levofloxacin hemihydrate.
