And the article contained the following:
11-Acyl-5,11-dihydro-6H-pyrido[2,3-b][1,4]benzodiazepin-6-ones I (R = 4-methylpiperazino, imidazolo, 2-methylimidazolo) were prepared via N-α-chloroacetylation and aminolysis. Other attempts at cyclization to form I are also reported. The experimental process involved the reaction of 3-Phenyl-1H-imidazo[4,5-b]pyridin-2(3H)-one(cas: 41010-50-8).Safety of 3-Phenyl-1H-imidazo[4,5-b]pyridin-2(3H)-one
