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., SDS of cas: 32974-92-8
Example 1872-(N-hydroxyethylbenzyl)aminoethyl-2-(3-ethyl)-pyrazylketone 8657 2-acetyl-3-ethylpyrazine (150 mg), hydroxyethylisopropylamine (149 mg), and paraformaldehyde (40 mg) were reacted in dioxane (0.2 ml) at 130 C. for 2 hours.NMR (CDCl3) 1.3 (m, 3H), 2.6 (m, 4H), 3.2 (m, 4H), 8.6 (s, 1H), 8.7 (s, 1H)TG 90.3 (3 mumol) 73 (10 mumol) 30 (30 mumol)SOCE 0 (10 mumol) 0 (30 mumol) 10 (100 mumol)IICR 20 (10 mumol) 10 (30 mumol) 100 (100 mumol)
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.
