Compound Q&A
How is 4-Bromo-6-chloropyridazin-3(2H)-one (CAS: 933041-13-5) typically synthesized?
Answer
4-Bromo-6-chloropyridazin-3(2H)-one is synthesized through a two-step process involving the bromination of 6-chloropyridazin-3(2H)-one followed by further modification. Commonly, this is achieved using N-bromosuccinimide (NBS) as a brominating agent in the presence of a radical initiator like AIBN. The reaction is carried out in an inert solvent such as dichloromethane (DCM) under UV light or heat, with high selectivity and good yield.
