A mixture of 28.0 g of p-phenetidine, 23.6 g of 2,6-dichloro-3-nitrobenzoic acid, and 80 ml of N,N-dimethylaniline was heated five hours on a steam bath. The resulting mixture was diluted with chloroform and extracted with 1N sodium hydroxide. Acidification of the aqueous extract yielded 6-chloro-2-[(4-ethoxyphenyl)amino]-3-nitrobenzoic acid as reddish brown crystals.
