Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors. It plays a key role in constructing pyrimidine-based scaffolds found in bioactive molecules. Commonly utilized in medicinal chemistry for modifying core structures to enhance potency and selectivity. Also employed in the preparation of antiviral and anticancer agents through cross-coupling and nucleophilic substitution reactions. Its protected amine group allows for selective functionalization, making it valuable in multi-step organic syntheses.
