Synthesis and some reactions of 4-nitro derivatives of imidazo[4,5-c]pyridin-2-ones
Imidazo[4,5-c]pyridine and its N-methyl derivatives do not undergo nitration, but the 2-oxo derivatives of these compounds are easily nitrated when heated. Some properties of the resulting 4-nitroimidazo[4,5-c]pyridin-2-ones have been studied.
