Procedure

To 280 mg of N,N-dimethylformamide were added 50 mg of 1-(6-amino-3,5-difluoro-4-methylpyridin-2-yl)-8-chloro-6,7-difluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid, 40 mg of 3-aminoazetidine dihydrochloride, and 120 mg of N-methylpyrrolidine, and the mixture was stirred at 90° C. for 1 hour. After adding 0.4 ml of ethanol, the mixture was allowed to cool. The precipitate was collected by filtration, and washed with ethanol and diisopropylether successively to obtain 45 mg of the title compound as a colorless powder.
