Application of 55557-52-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 55557-52-3, name is 3-Chloropyrazine-2-carbonitrile belongs to Pyrazines compound, it is a common compound, a new synthetic route is introduced below.
Step 1 : Preparation of 1 ‘ -(4-Methoxybenzyl)-l H-pyrazolo[3 ,4-b] pyrazin-3-amine(Exp-5-g23[0104] Into a vessel containing 50 mL ethanol was added 1.0 g of 3-chloropyrazine-2- carbonitrile (Exp-5-g22, 7.2 mmol), 1.1 g PMBNHNH2 (7.3 mmol) and 1.9 g K2C03 (14.2 mmol). The reaction mixture thus provided was heated to reflux and refluxing was continued for 6 hours, then the mixture was cooled to ambient temperature, filtered and the solid was washed sequentially with 10 mL H20 and 10 mL of methanol and dried yielding 1.0 g Exp-5-g23 (calculated yield 56%).
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, 3-Chloropyrazine-2-carbonitrile, other downstream synthetic routes, hurry up and to see.
