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, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. The trimethylsilyl group facilitates cross-coupling reactions, while the chloro substituent enables further derivatization through nucleophilic substitution or metal-catalyzed transformations. Commonly employed in research settings for the preparation of potential drug candidates targeting neurological disorders and cancer.
