Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic systems found in bioactive molecules. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to introduce aryl or amino groups. Also utilized in medicinal chemistry research for optimizing drug candidates targeting neurological disorders due to its ability to cross the blood-brain barrier.
