Can 2 - Aminotoluene be named as 2 - Methyl Aniline or 2 - Methyl benzenamine.
2-Aminotoluene makes sense, people will know what you're talking about, but aniline has higher priority as a parent structure than toluene, so according to IUPAC naming conventions you should go with 2-methylaniline.
Benzeneamide sounds like this (benzamide):
And therefore not appropriate.
o-Toluidine/2-toluidine is the common name.
