The synthesis of 9H-pyrrolo[1,2-a]-1,4-diazaindol-9-one was achieved either by an intramolecular electrophilic substitution of 2-chlorocarbonyl-3-N-pyrrolopyrazine 7 and 2-N-pyrrolidinocarbonyl-3-N-pyrrolopyrazine 8 or by the intramolecular nucleophilic substitution of 2-chloro-3-(2-pyrrolyl)pyrazine 12.
