With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.34231-77-1,Methyl pyridazine-4-carboxylate,as a common compound, the synthetic route is as follows.
To a solution of methyl pyridazine-4-carboxylate (0.4 g) in methanol (4.92 ml_) was added hydrazine hydrate (1.16 g) and the mixture was heated at reflux overnight. The reaction mixture was cooled and concentrated to afford pyridazine-4-carbohydrazide as a brown solid. (0715) NMR (400MHz, CDsOD) 9.52-9.48 (m, 1 H) 9.36 (dd, 114) 8.00 (dd, 1 H) (three NH protons missing), 34231-77-1
34231-77-1 Methyl pyridazine-4-carboxylate 12439252, apyridazine compound, is more and more widely used in various fields.
