An inexpensive and convenient production method of diphenylamine compounds is provided, that can solve problems in the conventional technology such as decrease in reactivity, restriction of substituents, high temperature, high pressure, by-products or the like. Further, diphenylamine compounds useful as intermediates of medicine and agricultural chemicals are provided. Diphenylamine compounds are produced, represented by general formula (3):
which is characterized by reacting aniline compounds represented by general formula (2):
under the presence of base and ethers solvent, with 2,6-dichloronitrobenzene compound represented by general formula (1):
and a diphenylamine compound represented by general formula (3).
