Nitration of 4, 5-dimethyl-carbethoxyaminobenzene with nitrosulfuric acid chiefly gives 2-nitro-4, 5-dimethyl-carbethoxy-aminobenzene with some 6-nitro and 2, 6-dinitro derivatives. Hydrolyses of these nitro compounds give 2-nitro-, 6-nitro- and 2, 6-dinitro-4, 5-dimethylaniline, respectively.
Acetylation of 6-nitro-4, 5-dimethylaniline with a mixture of acetic anhydride and glacial AcOH gives a mono-acetate of m.p. 106-7° and a diacetate of m.p. 114-5°.
