Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for targeted cancer therapies. Its structure allows for selective modification, making it valuable in creating biologically active molecules. Commonly employed in research settings for designing drugs that require a sterically hindered amine group and a protected heterocyclic core. Also utilized in the preparation of protease inhibitors and antiviral agents due to its ability to mimic peptide motifs while enhancing metabolic stability.
