General description

5-Amino-2-chloropyridine undergoes Suzuki-Miyaura coupling with sterically hindered 2,6-dimethylphenylboronic acid. It undergoes facile temperature dependent displacement of chloride by bromide via Sandmeyer reaction to yield 2,5-dibromopyridine.

Application

5-Amino-2-chloropyridine was used in the synthesis of [2H5]2-amino-l-methyl-6-phenylimidazo[4,5-b]pyridine. It was used in identification and evaluation of molecularly imprinted polymers for the selective removal of potentially genotoxic aminopyridine impurities from pharmaceuticals.
