The synthesis of 5‐azaindoles by substitution‐rearrangement of 7‐azaindoles upon treatment with certain primary amines

Abstract
Certain 4‐substituted 1H‐pyrrolo[2,3‐b]pyridines (7‐azaindoles) undergo a nucleophilic substitution‐rearrangement upon treatment with various primary amines at elevated temperatures to yield N‐1‐substituted 4‐amino‐1H‐pyrrolo[3,2‐c]pyridines (5‐azaindoles). Treatment of the same 7‐azaindoles with secondary amines under the same reaction conditions led to simple nucleophilic substitution products.
