The same ref. (Dye Chemistry) has preps for the ortho chloro p-toluidines. Again the Me group overrides the amino. Interesting because I have a copy
of a patent that teaches the opposite.
The 2-position of 6-nitro-4-toluenesulfonic acid is activated by both the Me and the nitro, and deactivated only by the sulfonic acid.
