Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors. It serves as a building block in medicinal chemistry for drugs targeting cancer and inflammatory diseases due to its ability to interact with specific enzyme active sites. Its structure allows for easy functionalization, making it valuable in creating compound libraries for drug discovery. Commonly employed in the preparation of potent and selective inhibitors of protein kinases such as JAK, ALK, and TRK, which are involved in signal transduction pathways linked to tumor growth and immune response.
