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 cross-coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in Suzuki and Buchwald–Hartwig reactions to introduce nitrogen-containing aromatic frameworks in drug candidates. Also utilized in the preparation of antitumor and antiviral agents due to its ability to modulate biological activity when incorporated into larger molecular scaffolds.
