Reference of 32974-92-8, The chemical industry reduces the impact on the environment during synthesis 32974-92-8, name is 1-(3-Ethylpyrazin-2-yl)ethanone, I believe this compound will play a more active role in future production and life.
(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 4-methylthiosemicarbazide dissolved in 20 ml of methanol,The solution prepared in the step (1) is dropwise added to a methanol solution containing 4-methylthiosemicarbazide, and the reaction mixture is stirred under reflux at 60 C for 24 hours to obtain a pale yellow precipitate.After the reaction, the mixture was cooled to room temperature, poured into a beaker and evaporated, and the resulting precipitate was filtered.Wash 3 times with absolute ethanol,After drying, the ligand L2 is obtained;Yield: 86.7%,
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.
