Adding a certain compound to certain chemical reactions, such as: 32974-92-8, name is 1-(3-Ethylpyrazin-2-yl)ethanone, 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 32974-92-8, Product Details of 32974-92-8
(1) 10 mmol of 2-acetyl-3-ethylpyrazine was dissolved in 20 ml of methanol,Stirring at 60 C for 15 min to prepare a solution;(2) taking 10 mmol of 3-pyrrol-3-thiosemicarbazide dissolved in 20 ml of methanol,The solution prepared in the step (1) is dropwise added to a methanol solution containing 3-pyrrol-3-thiosemicarbazide, and the reaction mixture is stirred under reflux at 60 C for 24 hours to obtain a pale yellow precipitate.After the reaction, it was cooled to room temperature and poured into a beaker to evaporate.The resulting precipitate was filtered and washed 3 times with absolute ethanol.After drying, the ligand L4 is obtained;
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, 1-(3-Ethylpyrazin-2-yl)ethanone, other downstream synthetic routes, hurry up and to see.
