Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex pyridine-containing pharmaceuticals and biologically active compounds. Its boronate ester group facilitates efficient carbon-carbon bond formation under mild conditions, making it valuable in drug discovery and development. Commonly employed in the preparation of kinase inhibitors and other therapeutic agents where precise molecular architecture is critical. The Boc-protecting group enhances stability and solubility during reaction sequences, allowing for selective deprotection and further functionalization in multi-step syntheses.
