2-Bromo-3-methylpyridine

It provides the essential pyridine ring of the molecule, with a bromine atom at the 2-position that serves as a reactive site for subsequent chemical transformations. Through cross-coupling reactions, such as Suzuki or Buchwald–Hartwig couplings, various substituents and heterocyclic fragments are attached to the pyridine core, allowing the stepwise assembly of the Crizotinib structure. By using 2-bromo-3-methylpyridine as a pre-functionalized building block, chemists can efficiently construct the molecule with high selectivity, making it a crucial intermediate in the drug’s synthesis. 2-Bromo-3-methylpyridine serves as a key synthetic intermediate in the production of Crizotinib, a tyrosine kinase inhibitor used in cancer therapy.
