New Heterocyclic Rearrangement: Transformation of 1-Substituted 4-(Alkylamino)-1H-pyrrolopyridines into 1-Substituted 4-(Alkylamino)-1H-pyrrolopyridines (5-Aza- to 7-Azaindoles)

Substitution of 1-alkyl-4-chloro-1H-pyrrolo<3,2-c>pyridines by primary alkylamines in excess afforded the expected 1-alkyl-4-(alkylamino)-1H-pyrrolo<3,2-c>pyridines and their 1-alkyl-4-(alkylamino)-1H-pyrrolo<2,3-b>pyridine isomers resulting from the reve
