Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors. Its structure supports the construction of complex molecules with biological activity, making it valuable in medicinal chemistry for drug discovery. The tert-butyl carbamate group acts as a protecting group for amines, enabling selective reactions during multi-step syntheses. It is also employed in the preparation of antiviral and anticancer agents where the methoxypyrimidine moiety is part of the active pharmacophore.
