Reaction Steps

To 160 mg of N,N-dimethylformamide were added 55 mg of 8-chloro-6,7-difluoro-1-(3,5-difluoro-6-isopropylamino-pyridine-2-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid, 35 mg of 3-aminoazetidine dihydrochloride, and 120 mg of N-methylpyrrolidine, and the mixture was stirred at 80° C. for 30 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 51 mg of the title compound as a colorless powder.
