34231-77-1 Methyl pyridazine-4-carboxylate 12439252, apyridazine compound, is more and more widely used in various fields.

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
