The synthesis of some derivatives of the novel heterocyclic ring system pyrido[3,4‐ d ][1]benzazepine is reported. Thus, pyrido[3,4‐ d ][1]benzazepin‐7‐one 6 was prepared by cyclisation of the Michael adduct 5 with ammonium ferric sulfate. Reaction of 6 with phosphorus pentasulfide gave the thiolactam 7 , which after methylation and subsequent reaction with amines furnished the amidines 10 .
