Adding a certain compound to certain chemical reactions, such as: 6966-01-4, name is Methyl 3-amino-6-bromopyrazine-2-carboxylate, 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 6966-01-4, Recommanded Product: Methyl 3-amino-6-bromopyrazine-2-carboxylate
Example 12.2: Preparation of 3-amino-6-methylpyrazine-2-carboxylic acid methyl ester; 3-Amino-6-bromopyrazine-2-carboxylic acid methyl ester (1.0 g), palladium acetate (0.101 g), and S-Phos (2′-dicyclohexylphosphino-2,6-dimethoxy-l,l’-biphenyl) were placed in a flask, with toluene (15 mL) and water (3 drops). Methyl boronic acid (0.394 g) and potassium phosphate (1.71 g) were added and the reaction mixture was refluxed for 24 hours. After allowing the reaction mixture to cool, the mixture was diluted with aqueous hydrochloric acid (IM) and extracted with ethyl acetate. The solvent was evaporated and the residue was purified by column chromatography on silica gel (eluent: diethyl ether) to give 3-amino-6-methylpyrazine-2-carboxylic acid methyl ester as a yellow solid (0.1 14 g).1H NMR (CDCl3): 2.40 (s, 3H), 3.92 (s, 3H), 6.21 (bs, 2H), 8.03 (s, IH) ppm.
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, Methyl 3-amino-6-bromopyrazine-2-carboxylate, other downstream synthetic routes, hurry up and to see.
