Used as an intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective modification, making it valuable in creating compounds with high target specificity. Commonly employed in medicinal chemistry for constructing drug candidates targeting neurological disorders and cancer. The tert-butyl ester group facilitates protection during multi-step synthesis, while the cyano-pyridinyl moiety contributes to binding affinity in receptor interactions.
