Copper-catalyzed coupling of o-toluidine (I) with 2-bromo-3-nitrobenzoic acid (II) gave the N-aryl-3-nitroanthranilic acid (III). Reductive cyclization with NaBH4 in the presence NaOEt produced the desired phenazine (V) along with amino anthranilic acid (VI), which were separated by fractional crystallization. Carboxylic acid (V) was then activated as the imidazolide (VI) upon treatment with carbonyl diimidazole. Finally, coupling of triethylenetetramine (VII) with two equivalents of imidazolide (VI) produced the title diamide.
