Versuchsvorschrift

In 10 ml of 50% water-containing ethanol is suspended 0.5 g of (R)-1-cyclopropyl-8-difluoromethoxy-7-(1-methyl-2,3-dihydro-1H-5-isoindolyl)-4-oxo-1,4-dihydro-3-quinolinecarboxylic acid and the suspension is then warmed to 50° C., after which 0.12 g of sulfuric acid is added thereto to form a uniform solution. Subsequently, the solution is stirred at the same temperature for 10 minutes and then filtered. The filtrate is cooled to room temperature and thereafter the crystals deposited are collected by filtration to obtain 0.34 g of (R)-1-cyclopropyl-8-difluoromethoxy-7-(1-methyl-2,3-dihydro-1H-5-isoindolyl)-4-oxo-1,4-dihydro-3-quinolinecarboxylic acid sulfate.
