                            It is an object of the present invention to provide 2-iminocarboxylic acid derivatives, and a practically suitable industrial method for producing benzazepinones in a short process under mild conditions. The present invention provides a method for producing a benzazepinone or a salt thereof, which comprises opening a ring of an isoquinoline derivative and subsequently converting the thus generated amine into a benzazepinone through lactamization reaction.
