Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of pyrimidine-based drugs. It serves as a building block for modifying the pyrimidine core structure, which is commonly found in antiviral, anticancer, and antimicrobial agents. The bromine atom allows for further functionalization through cross-coupling reactions, enabling the introduction of various substituents to tailor biological activity. The tert-butoxycarbonyl (Boc) group protects the nitrogen during synthesis and can be removed under mild acidic conditions, making it suitable for multi-step synthetic routes in medicinal chemistry.
