Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules that target central nervous system disorders. Its protected amine group and reactive alkyne functionality allow for selective coupling reactions, making it valuable in combinatorial chemistry and drug discovery. Commonly employed in palladium-catalyzed cross-coupling reactions such as Sonogashira coupling to introduce aromatic or heteroaromatic systems. Also utilized in the preparation of peptidomimetics and kinase inhibitors due to its structural rigidity and functional versatility.
