실험 절차

To 270 mg of N,N-dimethylformamide were added 110 mg of 1-(6-amino-3,5-difluoropyridine-2-yl)-8-bromo-6,7-difluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid, 50 mg of 3-hydroxyazetidine hydrochloride, and 100 mg of N-methy-lpyrrolidine together with 3 drops of ethanol, and the mixture was stirred at 85° C. for 25 minutes. After adding 0.5 ml of ethanol, the solution was allowed to cool, and the precipitate was collected by filtration and washed with ethanol and diisopropylether successively to obtain 101 mg of the title compound as a pale yellow powder.
