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 Heck reactions to build complex heterocyclic systems found in bioactive molecules. Also utilized in research settings for the design of new central nervous system agents due to its ability to cross the blood-brain barrier.
