Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic systems found in bioactive molecules. Commonly employed in cross-coupling reactions to introduce the pyrrolopyridine scaffold, which exhibits favorable binding properties with biological targets. Also utilized in medicinal chemistry research for optimizing drug candidates due to its metabolic stability and ability to enhance potency.
