How is (6-Chloroimidazo[1,2-b]pyridazin-2-yl)methanol (CAS: 1184916-24-2) typically synthesized?

(6-Chloroimidazo[1,2-b]pyridazin-2-yl)methanol is usually synthesized via a multistep process starting from 2-aminoimidazo[1,2-b]pyridazine. The key steps involve amidation, chlorination, and methylation reactions. Sodium hypochlorite is commonly used as a chlorinating agent, and the yield is typically around 70-80%. The reaction is performed in a controlled environment to ensure high selectivity and purity.
