実験手順

If, for example, the reaction mixture of 3-nitrobenzaldehyde and (S)-3-aminopyrrolidine is reacted with 8-chloro-1-cyclopropyl-6,7-difluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid in a one-pot reaction, the course of the reaction via the intermediately formed 8-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-7-[(S)-3-(3-nitrobenzylideneamino)-1-pyrrolidinyl]-4-oxo-3-quinolinecarboxylic acid to give 7-[(S)-3-amino-1-pyrrolidinyl]-8-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid hydrochloride can be represented by the following equation: ##STR19##
