Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and central nervous system agents. Its structure supports binding to biological targets involved in signal transduction pathways, making it valuable in drug discovery for oncology and neurological disorders. The amine and pyrrolidine functionalities allow for easy derivatization, enabling the creation of compound libraries for structure-activity relationship studies. It is also employed in the preparation of receptor agonists and antagonists due to its favorable pharmacokinetic properties and ability to cross the blood-brain barrier.
