Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and drug candidates. Its structure allows for selective modifications in organic reactions, making it valuable in forming nitrogen-containing heterocycles. Commonly employed in cross-coupling reactions, such as palladium-catalyzed transformations, to build complex aromatic systems found in medicinal chemistry. Also utilized in the preparation of protease inhibitors and receptor ligands due to its ability to mimic peptide motifs.
