How is 4-Bromo-2-pyridinol (CAS: 36953-37-4) typically synthesized?

4-Bromo-2-pyridinol is commonly synthesized via the bromination of 2-pyridol followed by hydrolysis of the bromopyridyl derivative. Commonly used brominating agents include phosphorus tribromide or bromine in the presence of appropriate solvents. The reaction is typically carried out under anhydrous conditions to improve yield and purity.
