Procedure

To 0.76 g (2.7 mmol) of the 1-cyclobutyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid in 10 ml of acetonitrile was added 0.4 g (2.7 mmol) of 1,8-diazobicyclo[5.4.0]undec-7-ene and 0.36 g (2.7 mmol and 0.36 g (2.7 mmol) of 3-[(ethylamino)methyl]pyrrolidine. The mixture was refluxed for 3.5 hours, cooled, filtered, and washed with ether to give 0.74 g of 1-cyclobutyl-7-[3-[(ethylamino)methyl]-1-pyrrolidinyl]-6,8-difluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid, mp 223°-225° C.
