Abstract

The reaction of 3-nitroquinoline 1-oxide with potassium cyanide in methanol was carried out producing 3-methoxycinchoninonitrile 1-oxide (I) and 3-methoxy-1H-pyrazolo [4, 3-b] quinoline-9-carboxamide (II). 5-Nitroquinoline 1-oxide gave 5-methoxyquinoline-6-carbonitrile 1-oxide (XIII) and 7-aminoisoxazolo [3, 4-f] quinoline 1-oxide (XIV), whereas 6-nitroquinoline 1-oxide gave methyl 5-cyano-6-methoxyquinaldimidate 1-oxide (VI), 5-cyano-6-methoxyquinaldamide 1-oxide (VII), and 1-hydroxy-6-nitrocarbostyril (VIII) by the similar type reactions. 4-Nitroquinoline 1-oxide produced 4-methoxyquinoline 1-oxide.
