Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization at multiple sites, making it valuable in medicinal chemistry for constructing nitrogen-containing heterocycles. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to introduce aryl or vinyl groups, enabling the creation of complex molecular architectures found in drug candidates. Also utilized in the preparation of pyridone-based compounds with potential antiviral, anticancer, or anti-inflammatory activity.
