A novel method is described for the synthesis of the key-intermediates of derivatives of the compound's ring system. Reaction of the intermediates with ortho esters furnishes the novel compounds, while S-methylation of the previously described thiones and subsequent aminolysis furnishes the novel type and imidazobenzotriazepines. Some ring transformation reactions of the type 8 compounds are also described.
