Reference of 54608-52-5, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 54608-52-5, name is 2-Hydrazinopyrazine, This compound has unique chemical properties. The synthetic route is as follows.
Step 1:; To a suspension of hydrazinopyrazine (400 mg, 3.57 mmol) in 50 ml Toluene was added 2(4-fluorphenyl)-1-(pyridin-4y1)ethanone (770 mg, 3.57 mmol) (J. Med Chem. 2003, 46, 4702) and p-toluenesulfonic acid (50 mg). The reaction mixture was refluxed with azeotropic removal of water. After 16 h, the reaction mixture was concentrated in vacuo to give the crude pyrazinylhydrazone (1.35 g) which was used in the next step without further purification.
The chemical industry reduces the impact on the environment during synthesis 2-Hydrazinopyrazine. I believe this compound will play a more active role in future production and life.
