    Abstract: This invention relates to the intramolecular oxidation and reduction of aromatic hydrocarbons containing at least one methyl group and a nitro group ortho to the methyl group. Further, it relates to preparing methyl o-amino arylcarboxylates and aromatic amines. The process comprises reacting aromatic hydrocarbons having at least one methyl group and a nitro group ortho to the methyl group in a solvent at a temperature of about 450* to 750* C. When the solvent is methanol, methyl o-amino arylcarboxylates useful in anesthetics, printing inks for polyethylene, and useful in the manufacture of azo dyes are produced. Novel substituted methyl anthranilates have been produced which have the foregoing uses. When the solvent is benzene, cyclohexane or toluene, aromatic amines are produced. The aromatic amines are useful as pesticides, antioxidants and as pickling inhibitors for aluminum and zinc and as curing agent for epoxy resins.
