Reaction Steps

formanilide method, where formic acid and aniline are used as starting materials to prepare formanilide, which in turn reacts with p-nitro-chlorobenzene in the presence of an acid-binding agent such as potassium carbonate, to produce 4-nitrodiphenylamine, and then, 4-nitrodiphenylamine is reduced by sodium sulfide to form 4-aminodiphenylamine;
