実験手順

In 192 ml of 50% water-containing ethanol is suspended 24 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 warmed to 40° C., after which 5.71 g of methanesulfonic acid is added to the warmed suspension to form a uniform solution. Subsequently, the solution is stirred at the same temperature for 10 minutes and thereafter filtered, and the filtrate is concentrated, after which the crystals deposited are collected by filtration to obtain 26.64 g of (R)-1-cyclopropyl-8-difluoromethoxy-7-(1-methyl-2,3-dihydro-1H-5-isoindolyl)-4-oxo-1,4-dihydro-3-quinolinecarboxylic acid methanesulfonate monohydrate.
