実験手順
907.4 g of moxifloxacin hydrochloride monohydrate and 9070 ml of absolute ethanol (K.F.<0.1%) were failed into a 10 liter jacketed reactor and equipped with a mechanical stirrer, reflux condenser, and thermometer. The suspension was brought to reflux with stirring and was kept in those conditions for 4 hours. The temperature was then reduced to 20° C. and the solid was filtered out and washed with 900 ml of absolute ethanol. The filtered solid was then discharged and dried under vacuum (30 mmHg) at 40° C. for 18 hours to give moxifloxacin hydrochloride form A having a water content of about 1% K.F.).
