1,7-Diazaperylene and various derivatives were synthesised in an upscaleable route from 1,5-diaminoanthraquinone and its Meerwein reaction with acrylonitrile and subsequent cyclisation with ammonia. The application of tert-butyl alcohol as the solvent led to a significant improvement in the Meerwein reaction.
