How is 5-(Benzyloxy)-2-bromopyridine (CAS: 630120-99-9) typically synthesized?

5-(Benzyloxy)-2-bromopyridine is typically synthesized through a multi-step process involving the protection of a pyridine ring with benzyloxy group followed by bromination. Commonly, benzyl bromide reacts with 2-hydroxy-5-pyridinecarboxylic acid to form the benzyloxy derivative. The bromination step is often carried out using N-bromosuccinimide (NBS) or hydrogen bromide in the presence of a catalyst like azobisisobutyronitrile (AIBN).
