Synthesis method of 6-chloroimidazo[1, 2-b]pyridazine-3-carbonitrile
-
Paragraph 0021-0032, (2021/02/06)
The invention relates to a synthesis method of 6-chloroimidazo[1, 2b]pyridazine-3-carbonitrile, which comprises the following steps of 1, adding N, N-dimethylformamide dimethyl acetal into a reactor to react with 3-amino-6-chloropyridazine, thereby obtaining an N, N-dimethyl-N'-3-(6-chloro-pyridazine)yl-formamidine intermediate; 2, adding a solvent into the N, N-dimethyl-N'-3-(6-chloro-pyridazine)yl-formamidine intermediate obtained in the step 1, mixing, adding bromoacetonitrile, reacting, adding alkali liquor, standing, separating out solid, and filtering to obtain a solid mixture, 3, completely dissolving the solid mixture obtained in the step 4 in ethyl acetate, washing with water and saturated edible salt water, drying, filtering, and removing ethyl acetate to obtain a crude product of 6-chloroimidazo[1, 2-b]pyridazine-3-carbonitrile, and 4, recrystallizing the crude product of the 6-chloroimidazo[1, 2-b]pyridazine-3-carbonitrile, and filtering to obtain a pure product of the 6-chloroimidazo[1, 2-b] pyridazine-3-carbonitrile. The method is short in overall process time, and the obtained product is stable in quality and high in purity.
