Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its indoline scaffold is valuable in medicinal chemistry for constructing nitrogen-containing heterocycles, which are common in drugs targeting cancer, inflammation, and neurological disorders. The bromo functional group allows for further cross-coupling reactions, such as Suzuki or Buchwald-Hartwig, enabling the introduction of diverse substituents. The tert-butyl carbamate (Boc) group serves as a protected amine, facilitating selective reactions in multi-step syntheses. Commonly employed in research settings for building complex molecules in drug discovery programs.
