With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.187973-60-0,6-Iodopyridazin-3-amine,as a common compound, the synthetic route is as follows.
187973-60-0, General procedure: Method H: to a solution of compound 12a (788 mg, 3.24 mmol)in n-butanol (12 mL) was added compound 3 (717 mg, 3.24 mmol).The mixture was refluxed for 16 h, evaporated to dryness, and theresidue was suspended in CHCl3. The solution was made alkalinewith a 30% ammonium hydroxide solution and extracted withCHCl3. The combined organic layers were dried over MgSO4,filtered, and evaporated under reduced pressure to give the desiredimidazo[1,2-b]pyridazine 13a (1.20 g, 100%) as a brown solid.
As the paragraph descriping shows that 187973-60-0 is playing an increasingly important role.
