Participants

Reaction Steps

To 0.76 g (2.33 mmol) of 6,7,8-trifluoro-1-(2,2,2-trifluoroethyl)-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid in 7.0 ml of acetonitrile was added 0.355 g (2.33 mmol) of 1,8-diazobicyclo [5.4.0]undec-7-ene in 5 ml of acetonitrile followed by 0.29 g (2.33 mmol) of 3-[(ethylamino)methyl]-pyrrolidine. The mixture was refluxed for one hour and kept at room temperature overnight. The solids were collected and washed with ether to give 0.77 g of 7-[3-[(ethylamino)methyl]-1-pyrrolidinyl]-6,8-difluoro-1,4-dihydro-4-oxo-1-(2,2,2-trifluoroethyl)-3-quinolinecarboxylic acid, mp 222°-224° C.
