Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and central nervous system agents. Its structure supports functionalization at multiple sites, making it valuable in medicinal chemistry for constructing bioactive molecules. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to introduce aryl or amino groups. Also utilized in the preparation of selective receptor modulators due to its rigid, heterocyclic framework that enhances binding affinity and metabolic stability.
