Procedure

To 0.80 g (2.8 mmol) of the 1-cyclopropyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid in 10 ml of acetonitrile and 0.43 g (2.8 mmol) of 1,8-diazobicyclo [5.4.0], undec-7-ene was added 0.35 g (3.1 mmol) of the N-ethyl-3-aminopyrrolidine. The mixture was refluxed for one hour and stirred overnight. The solids were filtered and washed with ether: acetonitrile (6:1), to give 0.81 g of the title compound, mp 236°-238° C.
