Procedure

To 100 mg of N,N-dimethylformamide were added 25 mg of 1-(4-amino-5-fluoropyrimidine-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 1 hour. 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 10 mg of the title compound as a colorless powder.
