Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 32974-92-8, name is 1-(3-Ethylpyrazin-2-yl)ethanone, A new synthetic method of this compound is introduced below., Safety of 1-(3-Ethylpyrazin-2-yl)ethanone
(1) Dissolve 10 mmol of 2-acetyl-3-ethylpyrazine in 20 mL of methanol and stir at 60 C for 15 min.Then, 20 mL, 10 mmol of 4,4-dimethyl-3-aminourea methanol solution was added dropwise to the above solution, and refluxed at 60 C.After the reaction was stirred for 12 h, it was cooled to room temperature, poured into a beaker and evaporated. The obtained pale yellow crystals were filtered and washed with methanol.Times, get the ligand (L4);
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
