Reaction Steps
A solution of 1.41 g (5.0 mmol) of 7-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine- 3-carboxylic acid, 1.10 (5.5 mmol) of 6,8-diazabicyclo[3.2.2]nonane, dihydrochloride, 2.26 ml (15 mmol) of 1,8-diazabicyclo[5.4.0]undec-7-ene, and 30 ml of acetonitrile was heated under reflux for 4 hr. After cooling to room temperature, the precipitated solid was collected to give 0.97 g of the title compound, mp 255°-258° dec.
