How is 3,5-Dibromoimidazo[1,2-a]pyridine (CAS: 69214-12-6) typically synthesized?

3,5-Dibromoimidazo[1,2-a]pyridine (CAS: 69214-12-6) is synthesized through a multi-step process involving bromination of imidazo[1,2-a]pyridine. Common methods include use of N-bromosuccinimide (NBS) or bromine in the presence of a Lewis acid like aluminum bromide (AlBr3) as a catalyst. The reaction is typically carried out in an inert solvent like dichloromethane (DCM) or carbon tetrachloride (CCl4). High yield and selectivity are often achieved with optimized conditions.
