Reaction Steps

A 200 mg portion of 1-ethyl-5,6,7,8-tetrafluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid was dissolved in 1 ml of 1-methylpyrrolidine with warming. A 130 mg portion of pyrrolidine was added dropwise, the reaction was allowed to stand one hour and then diluted with ether. The solid was collected, washed with ether and hexane, dried and recrystallized from a mixture of dichloromethane-acetone, giving 140 mg of the desired product as white crystals, mp >320° C.
