Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization at multiple sites, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in route-scanning for drug discovery due to the protected amine and reactive carbonyl group, which facilitate peptide-like coupling and cyclization reactions. Also utilized in the preparation of prodrugs and enzyme inhibitors where controlled polarity and steric bulk are required.
