Conditions

Temperature: 100 °C

Procedure

To 400 mg of N,N-dimethylformamide were added 100 mg of 8-chloro-6,7-difluoro-1-(3,5-difluoro-6-methylaminopyridin-2-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid, 60 mg of 3-aminoazetidine dihydrochloride, and 120 mg of N-methylpyrrolidine, and the mixture was stirred at 100° C. for 1 hour. 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 102 mg of the title compound as a colorless powder.
