実験手順
23.0 ml (0.0023 mole) of a 0.1N aqueous solution of sodium hydroxide were added to 1.00 g (0.00234 mole) of 5-amino-1-cyclopropyl-8-difluoromethoxy-6-fluoro-7-(3-methylpiperazinyl)-1,4-dihydro-4-oxoquinoline-3-carboxylic acid (prepared as described in Example 30), and the resulting insoluble material was removed by filtration. 0.11 g (0.00115 mole) of anhydrous magnesium chloride was added to the filtrate, and the mixture was stirred at room temperature for 90 minutes. At the end of this time, the resulting precipitate was collected by filtration and washed with water, to give 0.91 g of magnesium [5-amino-1-cyclopropyl-8-difluoromethoxy-6-fluoro-7-(3-methylpiperazinyl)-1,4-dihydro-4-oxoquinoline-3-carboxylate] as a yellow powder, melting at 291°-293° C. (with decomposition).
