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. 5932-27-4, name is Ethyl 1H-pyrazole-3-carboxylate belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. 5932-27-4
Ethylpyrazole-3-carboxylate (1.00 g, 7.14 mmol) was dissolved in acetonitrile (28 mL) N-iodosuccinimide (1.77 g, 7.85 mmol) and trifluoroacetic acid (0.16 mL, 2.14 mmol) were successively added thereto, followed by stirring at room temperature for 3 hours. After completion of the reaction, the reaction mixture was diluted with ethyl acetate and washed with a 5percent aqueous solution of sodium hydrogencarbonate and distilled water. The organic layer was dried over anhydrous sodium sulfate and concentrated. The resulting residue was purified by silica gel column chromatography (ethyl acetate: n-hexane = 4: 6) to give the title compound 75-a (1.69 g, 89percent) as a yellow solid .
The synthetic route of 5932-27-4 has been constantly updated, and we look forward to future research findings.
