N-Hydroxyquinolinimide 1 reacts with each of aromatic arnines, hydrazine hydrate and aromatic hydrocarbons to give arylcarbamoyl pyridines 2, pyrrolopyridines 3, pyridopyridazines 4 and pyridooxazinones 5 and 6. The heterocycles 5 and 6 can be transformed
AN UNUSUAL SYNTHESIS OF NICOTINAMIDES
Harrington, Philip M.
, p. 683 - 687 (2007/10/02)
Reaction of 2,3-pyridinedicarboxylic anhydride (1) with a substituted aniline (2) in acetic acid gave rise to a mixture of two products.These two products were identified as the cyclic imide (4) and nicotinamide (5).A mechanistic scheme consistent with empirical observations is proposed.
