실험 절차
To 0.75 g (2.75 mmol) of the 6,7,8-trifluoro-1,4-dihydro-1-methylamino-4-oxo-3-quinolinecarboxylic acid in 15 ml of acetonitrile was added 0.44 g (1.05 equivalent) of 1,8-diazobicyclo[5.4.0]undec-7-ene, and 0.352 g (1.0 equivalent) of N-ethyl-3-pyrrolidinemethanamine. The mixture was refluxed for one hour and then stirred at room temperature overnight. The solids were filtered to give 0.68 g of 7-[3-[(ethylamino)methyl]-1-pyrrolidinyl]-6,8-difluoro-1,4-dihydro-1-methylamino-4-oxo-3-quinolinecarboxylic acid, mp 222°-224° C.
