The stepwise synthesis of the N,N′-di- and N,N′,N″-tri-substituted tri-3-methyltrianthranilides (13)–(19) are described. The amino-acid derivatives (34), (38), and (45), which are the key acyclic precursors in the synthesis of the tri-3-methyltrianthranilides, were all prepared from 2-amino-m-toluic acid (22) and 2-nitro-m-toluoyl chloride as starting materials.
