実験手順

To 350 mg of N,N-dimethylformamide were added 80 mg of 1-(6-amino-3,5-difluoropyridin-2-yl)-8-chloro-6,7-difluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid, 60 mg of 3-amino-3-methylazetidine dihydrochloride, and 150 mg of N-methylpyrrolidine, and the mixture was stirred at 90° C. for 40 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 to obtain 64 mg of the title compound as a pale yellow powder.
