Discovery of 3-Amino-6-bromopyrazine-2-carboxylic acid

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-Amino-6-bromopyrazine-2-carboxylic acid, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 486424-37-7, name is 3-Amino-6-bromopyrazine-2-carboxylic acid, belongs to Pyrazines compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 486424-37-7, Recommanded Product: 3-Amino-6-bromopyrazine-2-carboxylic acid

HATU (3.54 g, 9.36 mmol) was added to a solution containing 1.64 g (7.5 mmol) of 3-amino-6-bromopyrazine-2-carboxylic acid in 25 mL of DMF. The reaction was stirred for 5 minutes before adding 2.5 mL (22.5 mmol) of N-methylmorpholine and 1.68 g (9.36 mmol) of 4-morpholinopyridin-3-amine. The reaction mixture was stirred for 16 h then quenched with 10 mL of saturated NH4C1 solution and then 10 mL of water. The mixture was extracted with EtOAc three times; the combined organics were washed with brine and then dried over Na2S04. The solvent was then evaporated and the residue was chromatographed (0% to 20% CH3OH / dichloro methane) to afford compound Int lB-1 as a yellow solid.
