In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 33332-25-1, name is Methyl 5-chloropyrazine-2-carboxylate belongs to pyrazines compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: Methyl 5-chloropyrazine-2-carboxylate
A 5 N sodium hydroxide solution (2 mL) was added to a solution of methyl 5-chloropyrazine-2-carboxylate (150 mg) in ethanol (4 mL), and the mixture was stirred at room temperature for five hours. Ethyl acetate and water were added to the reaction solution, and the aqueous layer was separated. The aqueous layer was made acidic with concentrated hydrochloric acid. Brine and ethyl acetate were added to the mixture, and the organic layer was separated. The organic layer was dried over anhydrous magnesium sulfate. The organic layer was concentrated to obtain the title compound (135 mg).1H-NMR (400 MHz, CDCl3) delta (ppm): 1.46 (t, J=7.2 Hz, 3H), 4.51 (q, J=7.2 Hz, 2H), 8.17 (s, 1H), 8.96 (s, 1H).
The synthetic route of 33332-25-1 has been constantly updated, and we look forward to future research findings.
