Reaction of various kinds of nitroquinoline with hydroxylamine in potassium hydroxide alkalinity afforded a novel product, furazanoquinoline, besides the known amino derivatives. The products obtained were furazano[3, 4-f]quinoline (XII) from 5-nitroquinoline (VIII) and 6-nitroquinoline (XIII), and furazano[3, 4-h]quinoline (XVII) from 7-nitroquinoline (XV) and 8-nitroquinoline (XVIII). The same reaction progresses with 3-nitroquinoline (II) but the nitro group is substituted with the reagent in the case of 4-nitroquinoline (V). 6, 8-Diamino-5-nitroquinoline (XI) obtained by the reaction of VIII with hydroxylamine was found to be formed via 6-amino-5-nitroquinoline (X).
