3-diazopyrroles of type 5 were prepared and refluxed in acetic acid.In the case of 5a, an intermolecular coupling reaction between the diazonium group and the methoxyphenyl substituent in the 2-position leads to the 1H-pyrrolocinnoline derivative 6, whilst in the case of 5b an intermolecular coupling with the acetyl group in the 4-position affords the pyrrolopyridazine derivative 7.
