Application of 33332-28-4, The chemical industry reduces the impact on the environment during synthesis 33332-28-4, name is 2-Amino-6-chloropyrazine, I believe this compound will play a more active role in future production and life.
Pre Step A 6-(Methyloxy)-2-pyrazinamine A mixture of 6-chloro-2-pyrazinamine (200 mg, 1.544 mmol) and sodium methoxide (250 mg, 4.63 mmol) in methanol (3.9 ml) was heated to 130 C. via a microwave reactor for 60 min. The crude product mixture was purified by RP-HPLC to give 6-(methyloxy)-2-pyrazinamine (154 mg, 1.231 mmol, 80% yield). MS (ES+) m/z 125.8 (MH+).
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, 2-Amino-6-chloropyrazine, other downstream synthetic routes, hurry up and to see.
