실험 절차

A solution of 0.54 g (2.0 mmol) of 1-ethyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid, 0.57 g (2.2 mmol) of 2,5-diazabicyclo(2.2.1)heptane dihydrobromide [P. S. Portoghese and A. A. Mikhail, J. Org. Chem., 31, 1059 (1966)], 0.90 ml (6.0 mmol) of 1,8-diazabicyclo(5.4.0)undec-7ene, and 20 ml of acetonitrile was heated under reflux for one hour and stirred at room temperature for two hours. The reaction mixture was filtered and the solid was washed with ethanol to give 0.60 g of the title compound, mp 275° C.
