Abstract
Ethyl 9-cyclopropyl-4-fluoro-6-oxo-6,9-dihydro[l,2,5]oxadiazolo[3,4-h]quinoline-7-carboxylate N(3)-oxide (3) is synthesized via pyrolysis of the 7-azido-8-nitroquinoline-3-carboxylate precursor (6). Acid-catalyzed hydrolysis of the product (3) afforded the corresponding carboxylic acid (4), of which structures are confirmed by spectroscopic means including X-Ray measurements.
