実験手順

A mixture of 1.40 g (5.0 mmole) of 1-ethyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid, 2.0 g (8 mmole) of 8-methyl-3,8-diazabicyclo[3.2.1]octane dihydrochloride [P. A. Sturm et al., J. Med. Chem., 17, 481 (1974)], 2.0 ml (13.3 mmole) of 1,8-diazobicyclo[5.4.0]undec-7-ene, and 75 ml of acetonitrile was heated under reflux for 1.5 hr and then stirred at room temperature for 22 hours. The reaction mixture was evaporated to dryness and the residue was recrystallized from 2-propanol to give 0.84 g of the title compound, mp 184°-187° C.
