Abstract
Ethyl 7-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-5-methyl-4-oxo-1,8-naphthyridine-3-carboxylic acid has been prepared by a route involving masking of the C 2,3 double bond through reduction, followed by regiosselective deprotonation of the C 5 position and methylation and then regeneration of the C 2,3 double bond via selenation, oxidation, and syn-elimination
