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 biologically active molecules. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build complex heterocyclic systems found in drug candidates. Also utilized in research settings for the design of new central nervous system agents due to its pyrrolopyridine core, which can mimic purine moieties in biochemical pathways.
