Conditions

Temperature: 85 °C

Procedure

To 90 mg of N,N-dimethylformamide were added 25 mg of 1-(6-amino-5-fluoro-3-methylpyridin-2-yl)-8-chloro-6,7-difluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid, 25 mg of 3-(methylamino)azetidine dihydrochloride, and 70 mg of N-methylpyrrolidine, and the mixture was stirred at 85° C. for 45 minutes. After adding 0.2 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 20 mg of the title compound as a colorless powder.
