The synthesis of 2-phenyl-3-aminopyridine, a key intermediate in the preparation of 2- phenyl-3-aminopiperidine, from 2-chloro-3-aminopyridine is described using an imine as a protecting group for an aminopyridine. The in situ protection of 2-chloro-3-aminopyridine with benzaldehyde followed by Suzuki coupling with phenylboronic acid and subsequent acid hydrolysis provided the titled compound in a single, high-yielding step from ...
