Reference of 123-32-0, The chemical industry reduces the impact on the environment during synthesis 123-32-0, name is 2,5-Dimethylpyrazine, I believe this compound will play a more active role in future production and life.
Preparation of 3,6-dimethyl-2- (4-methoxy) benzoyl pyrazine, comprising the steps of: (1) 2,5-dimethyl pyrazine take 0.2mmol, 4- methoxybenzoyl acid 0.4mmol, 0.02 mmol silver phosphate, potassium persulfate 5mL reaction tube was placed 0.4mmol, 1.4mL was added di methylene chloride, 0.6 mL of distilled water was added, and the mixture was placed in an oil bath at 40 heated, reaction 24h, cooled to room temperature to obtain a reaction solution;(2) The step (1) the resulting reaction mixture was directly concentrated to give a concentrate, the concentrate with ethyl acetate / petroleum ether = 1/2 (v / v) as the developing solvent, separation by thin layer chromatography to give 56mg target The product, in 80% yield.
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, 2,5-Dimethylpyrazine, other downstream synthetic routes, hurry up and to see.
