4-Bromo-2-methylpyridine is a valuable substituted bromopyridine heterocyclic building block.

The bromine atom at 4-position of pyridine ring has good reaction activity for nucleophilic substitution. It can undergo Suzuki coupling, Heck reaction, Sonogashira and Buchwald-Hartwig cross-coupling reactions. It is widely used as key intermediate for synthesizing kinase inhibitors, anticancer drugs, anti-inflammatory agents and CNS medicinal molecules. Also applied in medicinal chemistry compound library construction and structure-activity relationship research, as well as agrochemical intermediate synthesis.
