Versuchsvorschrift
In 12 ml of pyridine were dissolved 0.8 g (0.0026 mole) of 6,7-difluoro-8-trifluoromethyl-1,4-dihydro-1-methyl-4-oxoquinoline-3-carboxylic acid and 2.1 g (0.0118 mole) of 1-(2-pyrimidinyl)homopiperazine, the mixture was stirred at 105° C. for 3 hours, and then the solvent was removed by evaporation under reduced pressure. The residue was applied to silica gel column chromatography (eluent; a chloroform:methanol=9.5:0.5 mixed solution) to obtain 0.45 g of 6-fluoro-8-trifluoromethyl-1,4-dihydro-4-oxo-1-methyl-7-[4-(2-pyrimidinyl)homopiperazin-1-yl)quinoline-3-carboxylic acid as yellow powder.
