Adding a certain compound to certain chemical reactions, such as: 56423-63-3, name is 2-Bromopyrazine, 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 56423-63-3, Recommanded Product: 2-Bromopyrazine
The above oily liquid was dissolved in 10 mL of ethylene glycol dimethyl ether and 2 mL of water, and 2-bromopyrazine (276 mg, 1.74 mmol), Pd(PPh3)4 (50 mg, 0.043 mmol) and Na2CO3 (460 mg, 4.34 mmol), and the reaction was stirred at 100 C for 2 hours under nitrogen atmosphere. After cooling to room temperature, the reaction solution was poured into 60 mL of water and extracted three times with 20 mL of ethyl acetate. The combined ethyl acetate was washed with brine and dried over anhydrous sodium sulfate. Concentration by filtration, column chromatography (petroleum ether / ethyl acetate, 1/1) gave 65 mg of white solid powder as compound A-1a.
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-Bromopyrazine, other downstream synthetic routes, hurry up and to see.
