Electric Literature of 933190-51-3, The chemical industry reduces the impact on the environment during synthesis 933190-51-3, name is 8-Bromo-6-chloroimidazo[1,2-b]pyridazine, I believe this compound will play a more active role in future production and life.
Preparation of 6-chloro-N-cyclopropylimidazo[1,2-b]pyridazin-8-amine To a solution of 8-bromo-6-chloroimidazo[1,2-b]pyridazine (1.00 g, 3.21 mmol, 1.0 equiv) and p-TSA (611 mg, 3.21 mmol, 1.0 equiv) in DMSO (10.0 mL) was added cyclopropylamine (1.13 mL, 16.1 mmol, 5.0 equiv) and heated to 100 C. for 24 h. Purification by column chromatography using 50% ethyl acetate in hexanes elution gave 536 mg of the white solid, 80%.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 8-Bromo-6-chloroimidazo[1,2-b]pyridazine, other downstream synthetic routes, hurry up and to see.
