Reaction Steps

To 110 mg of N,N-dimethylformamide were added 23 mg of 1-(4-amino-5-fluoropyridine-2-yl)-8-chloro-6,7-difluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid, 20 mg of 3-aminoazetidine dihydrochloride, and 50 mg of N-methylpyrrolidine, and the mixture was stirred at 90° C. for 20 minutes. After adding 500 mg of ethanol, the mixture was allowed to cool, and the precipitate was collected by filtration and washed with ethanol and diisopropylether successively to obtain 23 mg of the title compound as a colorless powder.
