Adding a certain compound to certain chemical reactions, such as: 16298-03-6, name is Methyl 2-aminopyrazine-3-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 16298-03-6, Recommanded Product: Methyl 2-aminopyrazine-3-carboxylate
Example 58; Step 1; A solution of bromine (10 mL, 190 mmol) in acetic acid (10 mL) was added dropwise to a solution of 1 (20 g, 130 mmol) in glacial acetic acid (100 mL) at 45¡ã C. The resulting mixture was stirred at 25¡ã C. for 30 min. After completion of reaction (reaction progress was monitored by TLC), the solution was diluted with water (600 mL) and then stirred at RT for another 30 min. A yellow solid precipitated out, which was filtered, washed with water and dried to afford compound 2 as yellow solid (28.5 g, 93percent). MS m/z (ES): 232 (M+H)+.
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 2-aminopyrazine-3-carboxylate, other downstream synthetic routes, hurry up and to see.
