Abstract

Reaction of 2-chloro-N-(p-nitrophenacyl)pyridinium bromide with potassium cyanate in acetonitrile produces 2-(p-nitrophenyl)oxazolopyridinium bromide. Performing the same reaction in methanol N-(p-nitrophenacyl)pyrid-2-one was isolated. The structures of the obtained products were proved by X-ray structural data.
