On August 17, 2006, Scott, Jeremy P. published an article.Name: 3-Phenyl-1H-imidazo[4,5-b]pyridin-2(3H)-one The title of the article was Two-step synthesis of 3-aryl-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-ones. And the article contained the following:
One-pot tandem palladium-catalyzed amination and intramol. amidation of tert-Bu (2-chloropyridin-3-yl)carbamate with substituted primary anilines allows for the preparation of 3-arylated 1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-ones (49-90% yield) in two steps from com. available materials. The experimental process involved the reaction of 3-Phenyl-1H-imidazo[4,5-b]pyridin-2(3H)-one(cas: 41010-50-8).Name: 3-Phenyl-1H-imidazo[4,5-b]pyridin-2(3H)-one
The Article related to chloropyridinylcarbamate primary aniline tandem amination intramol amidation, imidazopyridinone dihydro preparation, Heterocyclic Compounds (More Than One Hetero Atom): Imidazoles and other aspects.Name: 3-Phenyl-1H-imidazo[4,5-b]pyridin-2(3H)-one
