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 creating targeted therapies. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build complex heterocyclic systems found in bioactive molecules. Also utilized in medicinal chemistry research for optimizing drug candidates due to its favorable electronic and steric properties.
