Used in Suzuki-Miyaura cross-coupling reactions to introduce the 4-methylindole moiety into complex organic molecules. Its boronic acid group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in pharmaceutical synthesis, particularly for constructing indole-based drug candidates. The Boc-protecting group stabilizes the nitrogen during reactions and can be easily removed later in the synthesis. Commonly applied in the development of bioactive compounds and heterocyclic systems in medicinal chemistry research.
