Used as a key intermediate in pharmaceutical synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct biaryl compounds. Its indole core and boronic acid functionality make it valuable for forming carbon-carbon bonds in the development of bioactive molecules and drug candidates. The silyl protecting group enhances stability and selectivity during reaction sequences, allowing for controlled functionalization in complex synthetic pathways. Commonly applied in the preparation of serotonin receptor modulators and other neuroactive agents.
