실험 절차

In 3 ml of ethanol was suspended 0.30 g of ethyl 1-cyclopropyl-6-fluoro-8-methyl-7-[2-(p-toluenesulfonyl)isoindolin-5-yl]-1,4-dihydro-4-oxoquinoline-3-carboxylate, and 3 ml of 1N aqueous sodium hydroxide solution and 3 ml of dioxane were added to the suspension, after which the resulting mixture was stirred at room temperature for two hours. To the reaction mixture was added 3 ml of 1N hydrochloric acid, and the crystals thus formed were collected by filtration, to obtain 0.27 g of colorless, crystalline 1-cyclopropyl-6-fluoro-8-methyl-7-[2-(p-toluenesulfonyl)isoindolin-5-yl]-1,4-dihydro-4-oxoquinoline-3-carboxylic acid.
