実験手順

14.32 g (45 mmol) of ethyl 8-cyano-1-cyclopropyl-6,7-difluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylate, 6.31 g (50 mmol) of (1S,6S)-2,8-diazabicyclo[4.3.0]nonane and 10.22 g (101 mmol) of triethylamine are boiled under reflux in 270 ml of acetonitrile for 4 hours. The reaction mixture is left to stand at room temperature for some hours and the solid which has crystallized out is filtered off with suction, rinsed with acetonitrile and dried. 15.6 g of a beige solid are obtained (82% of theory).
