Procedure

To 280 mg of N,N-dimethylformamide were added 80 mg of 1-(6-amino-3,5-difluoropyridine-2-yl)-8-chloro-6,7-difluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid, 100 mg of 3-(aminomethyl)azetidine dihydrochloride, and 200 mg of N-methylpyrrolidine, and the mixture was stirred at 90° C. for 25 minutes. After adding 0.5 ml of ethanol, the mixture was allowed to cool, and the precipitate was collected by filtration and washed with ethanol and diisopropylether successively to obtain 42 mg of the title compound as a colorless powder.
