On September 30, 1976, Yutilov, Yu. M.; Svertilova, I. A. published an article.Computed Properties of 41010-50-8 The title of the article was New method for preparing condensed imidazolones. And the article contained the following:
Imidazoles I and II (X = CH, N; R = H, Cl; R1 = H, Me, Et, R2 = H, Me, Ph, CH2Ph) were obtained in 80-99% yields by treatment of the corresponding o-phenylenediamine or diaminopyridine with EtO2COCO2Et. The experimental process involved the reaction of 3-Phenyl-1H-imidazo[4,5-b]pyridin-2(3H)-one(cas: 41010-50-8).Computed Properties of 41010-50-8
The Article related to cyclocondensation phenylenediamine pyrocarbonate, pyridinediamine cyclocondensation polycarbonate, imidazolone condensed, Heterocyclic Compounds (More Than One Hetero Atom): Imidazoles and other aspects.Computed Properties of 41010-50-8
