Reaction Steps

To 250 mg of N,N-dimethylformamide were added 80 mg of 1-(6-amino-5-fluoropyridine-2-yl)-8-bromo-6,7-difluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid, 80 mg of 3-methylaminoazetidine dihydrochloride, and 200 mg of N-methylpyrrolidine, and the mixture was stirred at 85° C. for 10 minutes. After adding 0.5 ml of ethanol, the solution was allowed to cool, and the precipitate was collected by filtration and washed with ethanol and diisopropylether successively to obtain 66 mg of the title compound as a colorless powder.
