The purpose of the present invention is to provide a method for easily producing a diaminobenzene compound and a benzimidazole compound at low cost. The present invention provides a method for producing a diaminobenzene compound or N-protected aminobenzene compound represented by formula (2), the method comprising bringing an aminonitrobenzene compound or N-protected nitrobenzene compound represented by formula (1) into contact with an alkali metal salt of dithionous acid. Also provided is said method in which a deprotection reaction is conducted according to need. (In formulae (1) and (2), nis an integer of 1-4; R1 is a C1-6 alkyl, C1-6 alkoxy, C2-6 acyloxy, C2-6 alkoxycarbonyl, or nitro group or a halogen atom, and when n>=2, then the R1 moieties may be the same or different; and RA isa hydrogen atom or a protective group.)
