Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors. Its structure supports binding to enzyme active sites, making it valuable in creating drugs targeting cancer and inflammatory diseases. The tert-butyl ester group aids in solubility and stability during synthesis, while the cyano-pyridine moiety contributes to target selectivity. Commonly employed in medicinal chemistry for optimizing drug candidates due to its favorable pharmacokinetic properties.
