4,5-Dimethoxy-2-nitrobenzoic acid (I) was converted to the corresponding acid chloride (II) upon treatment with SOCl2, and this was further coupled to aniline (III), producing amide (IV). Catalytic hydrogenation of the nitro group of (IV) afforded amine (V). Acid chloride (VII) --obtained by chlorination of 3-quinolinecarboxylic acid (VI) with SOCl2-- was then condensed with amine (V) to furnish the title diamide.
