| titleOfInvention | The synthetic method of 3-iodine imidazo [1,2-b] pyridazine |
| abstract | The present invention relates to a kind of synthetic method of 3-iodine imidazo [1,2-b] pyridazine.With 3-amino pyridazine, aqueous chloroacetaldehyde solution, N-N-iodosuccinimide for raw material, the ratio of 3-amino pyridazine, both monochloroacetaldehydes amount of substance is 1:0.8-3.5,3-amino pyridazine is 1:0.65-2.1 with the ratio of N-N-iodosuccinimide amount of substance, in suitable solvent, 3-iodine imidazo [1 is generated in 40-150 DEG C of reaction, 2-b] the thick product of pyridazine, after purifying, obtain 3-iodine imidazo [1,2-b] pyridazine sterling.Raw material ratio of the present invention is comparatively easy to get, reasonable price, does not simultaneously use heavy metal and corrosive gases in preparation feedback, reaction temperature and, do not have special requirement to reflection equipment, common corrosion resistant apparatus can be produced, and reaction conditions of the present invention is moderate in addition. |
