実験手順

In 0.75 ml of acetic acid 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-quinoline-carboxylic acid and the suspension is warmed to 80° C. to form a uniform solution. Subsequently, the solution is filtered at the same temperature and then 2.5 ml of ethanol is added to the filtrate, after which the crystals deposited are collected by filtration to obtain 0.24 g of (R)-1-cyclopropyl-8-difluoromethoxy-7-(1-methyl-2,3-dihydro-1H-5-isoindolyl)-4-oxo-1,4-dihydro-3-quinolinecarboxylic acid acetate.
