A new synthetic route of 6164-79-0

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 6164-79-0, its application will become more common.

Some common heterocyclic compound, 6164-79-0, name is Methyl 2-pyrazinecarboxylate, molecular formula is C6H6N2O2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. COA of Formula: C6H6N2O2

Pyrazine-2-carboxylic acid hydrazide. To a stirred solution of pyrazine-2-carboxylic acid methyl ester (11.1 g, 80 mmol) in 140 mL OF ETOH was added hydrazine hydrate (15.6 ML, 320 mmol). The resultant solution was heated to reflux for 2h. The solvent was removed under reduced pressure and dried under high vacuum to yield the title amide (11.1 g, 100%) as a white solid. The product was used in subsequent steps without purification.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 6164-79-0, its application will become more common.
