Adding a certain compound to certain chemical reactions, such as: 15707-23-0, name is 2-Ethyl-3-methylpyrazine, 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 15707-23-0, Computed Properties of C7H10N2
A mixture of 2-methyl-3-ethylpyrazine (22.35g, 183mmol), selenium dioxide (30g, 270mmol), and diatomaceous earth (30g) in dioxane (250ml) was heated at reflux for 18 hours. The mixture was allowed to cool and the solid material removed by filtration through diatomaceous earth. The filter pad was washed with methanol several times and the volatiles removed from the combined filtrate by evaporation. The residue was purified by chromatography on silica gel eluting eluting with EtOAC/hexanes (0:100 increasing in polarity tol5:85) to give 3-ethylpyrazine-2-carboxaldehyde (3.Og, 12%); NMR Spectrum 1.22 (t, 3H), 3.19 (q, 2H), 8.78 (s, IH), 8.80 (s, IH), 10.10 (s, IH).
