A process for the production of nitrodiarylamines by the reaction of a nitroarene with an aromatic primary amine in a suitable solvent and in the presence of a base capable of abstracting a proton from said aromatic primary amine, is disclosed. The reaction is carried out at a reaction temperature of 20-70°C over a period of 6-24 hours and in a substantially oxygen-free atmosphere. The produced nitrodiaryl amines are useful as intermediates for the production of dyestuffs and rubber antidegradants.
