Abstract: Substituted anilino-nicotinic acid derivatives are readily prepared from the condensation of two intermediates, 2-alkyl-3-perfluoroalkyl-anilines and alkyl 2-chloronicotinates. The 2-alkyl-3-perfluoroalkyl-aniline intermediate can be prepared via a novel three step synthesis. 3-Perfluoroalkyl-anilines are reacted with an amine directing protecting group reagent to protect the amine.

The 2-alkyl-3-perfluoroalkyl-aniline intermediate is condensed with the alkyl 2-chloronicotinate to form the anilino-nicotinic acid derivative.
