ABSTRACT:
This invention relates to a novel process for preparing novel N-cyclopropyl intermediates useful for preparing certain of the 1,7-disubstituted-6-fluoro-1,4-dihydroquinol-4-one-3-carboxylic acid derivatives of this invention which contain a cyclopropyl substituent at the 1 position as well as other 1,4-dihydroquinol-4-one-3-carboxylic acid derivatives so substituted with cyclopropyl.
