Abstract
SummaryThe nitro group in 4-nitroimidazo[4,5-c]pyridin-2-ones is rather labile and may be replaced upon heating with hydrohalic acids to give the corresponding 4-halides. A methyl group at N(3) leads to a sharp increase in the lability of the nitro group, but the isomeric 5-vitro derivatives do not react with hydrobromic or hydrochloric acids. Some reactions and transformations of 4-chloroimidazo[4,5-clpyridin-2-one are examined.
