Versuchsvorschrift

A suspension of 17.2 g (50.2 mmol) of ethyl 5-amino-8-chloro-1-cyclopropyl-6,7-difluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylate in 100 ml of 6M hydrochloric acid was refluxed for three hours. The mixture was cooled to room temperature, and the solids were filtered, washed with water and ether, and dried to give 14.2 g of the title compound.
