Reaction Steps
A mixture of 0.6 g (2.1 mmoles) of 1-cyclopropyl-1,4-dihydro-6,7,8-trifluoro-4-oxo-3-quinolinecarboxylic acid with 0.25 g (4.4 mmoles) of azetidine, 8 ml of pyridine and 1 ml of triethylamine is maintained at 110°-120° C. for 2 hours in a closed vessel. After cooling, evaporating under vacuum, filtering and washing, 0.6 g (88%) of 1-cyclopropyl-6,8-difluoro-1,4-dihydro-7-(1-azetidinyl)-4-oxo-3-quinolinecarboxylic acid are obtained, melting at 289°-93° C.
