Abstract

Nine 3-nitropyridine compounds and 4-nitroisoquinoline have been aminated in the 6- position (for 4-nitroisoquinoline in the 1-position) by vicarious nucleophilic substitution reactions. Two amination reagents were used, hydroxylamine and 4-amino-1, 2, 4-triazole. The yields were from moderate to good. Use of hydroxylamine gave an easy work-up procedure by which almost pure product was obtained directly, but 4-amino-1, 2, 4-triazole ...
