We have synthesized and characterized a series of alkyl and aryl-(4-methyl-6-nitro-quinolin-2-yl)amines through a high-yield, three-step procedure starting from 4-methylquinolin-2-ol. Nitration using concentrated nitric/sulfuric acids, followed by chlorination in phosphorus oxychloride, yielded 2-chloro-4-methyl-6-nitroquinoline. All of the intermediates and aminated products have been characterized by multinuclear ((1)H and (13)C) NMR spectroscopy, elemental analysis, and, in the case of the two title compounds (ethyl and cyclohexyl-(4-methyl-6-nitro-quinolin-2-yl)amine), a single crystal X-ray structure was obtained to verify the nature of the new materials.
