Versuchsvorschrift

A mixture of 8-chloro-1-ethyl-6,7-difluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid (0.25 g), cis-3-t-butoxycarbonylamino-4-methylpyrrolidine (0.21 g), DBU (0.15 g) and anhydrous acetonitrile (4 ml) was refluxed for 2.5 hours. Then, the reacting mixture was treated as described in example 22 to give the title compound (0.1 g) as white powder, mp 222°-224° C. (decompd.).
