Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for targeted cancer therapies. Its structural features allow for selective modification in drug design, enhancing metabolic stability and bioavailability. Commonly employed in medicinal chemistry research to construct complex molecules requiring sterically hindered amine functionalities. Also utilized in the preparation of proteolysis-targeting chimeras (PROTACs) due to its favorable protecting group characteristics and compatibility with multi-step synthetic routes.
