실험 절차

In 9.4 ml of 25% water-containing ethanol is suspended 1.2 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 2.57 ml of 1 mole/liter aqueous sodium hydroxide solution is added thereto, after which the resulting mixture is exposed to ultrasonic wave for 1 hour to form a uniform solution. Subsequently, the reaction mixture is washed twice with chloroform, and concentrated, and the crystals deposited are collected by filtration to obtain 0.49 g of sodium (R)-1-cyclopropyl-8-difluoromethoxy-7-(1-methyl-2,3-dihydro-1H-5-isoindolyl)-4-oxo-1,4-dihydro-3-quinolinecarboxylate.
