실험 절차
To 0.80 g (2.46 mmol) of 1-cyclohexyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid in 15 ml of acetonitrile was added 0.37 g (2.46 mmol) of 1,8-diazobicyclo[5.4.0]undec7-ene and 0.33 g (2.58 mmol) of 3-[(ethylamino)methyl]pyrrolidine. The mixture was refluxed for one hour, cooled, filtered, and the solids washed with ether to give 0.86 g of 1-cyclohexyl-7-[3-(ethylamino)methyl]-1-pyrrolidinyl]-6,8-difluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid, mp 194°-196° C.
