Abstract
Substd. aniline derivs. of formula (I), in which R1 and R2 are H, methyl, CF3 or chloro, are made by reaction of o-chloro benzoic acid with a substd. aniline of formula (II), in inert organic solvent in presence of a catalyst, e.g. copper, its salts or oxides, and a base as acid acceptor, at reflux temp. The corresp. salt is obtd. by treating the acid formed with the appropriate base.
