Upstream Synthesis Route

The upstream synthesis of 8-Bromo-6-chloroimidazo[1,2-b]pyridazine typically involves the following steps:

1. Synthesis of the pyridazine core: Start from a 1,2-dicarbonyl compound with appropriate substituents to form the pyridazine ring via condensation with hydrazine.

2. Introduction of the imidazole ring: This can be achieved by cyclodehydration of an amino pyridazine with an α-haloketone or α-haloaldehyde to form an imidazo[1,2-b]pyridazine system.

3. Halogenation: Sequential introduction of bromine and chlorine atoms into the imidazo[1,2-b]pyridazine framework at the desired positions using regiospecific halogenating agents, such as N-bromosuccinimide (NBS) for bromination, and suitable chlorinating agents for chlorination.

Optimization of reaction conditions such as temperature, solvent, and reaction time is essential for achieving the desired regioselectivity and yields for each step. It is important to note that protecting groups may be required to prevent side reactions, and purification steps such as recrystallization or chromatography are often necessary to obtain the final product with high purity.
