Imidazobenzodiazepine derivatives were obtained by cyclization of the condensation products 7-amino-2,5,6-trimethylbenzimidazole with acetylacetone and ethyl acetoacetate. By careful examination of spectroscopic data and the open-chain intermediate isolation, we have identified the formed compound structure.
