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. 951626-95-2, name is Ethyl 4-oxo-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazine-2-carboxylate belongs to Pyrazines compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 951626-95-2
To a solution of cyclopropylmethyl bromide (0.101 g, 0.75 mmol) and ethyl 4-oxo-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazine-2-carboxylate (31.4 mg, 0.150 mmol) in acetonitrile (2 mL) was added cesium carbonate (147 mg, 0.45 mmol). The reaction mixture was heated overnight at 70 C. Upon cooling to room temperature, the insolubles were removed by filtration and the solvent evaporated to dryness to afford crude Intermediate 33.
The synthetic route of 951626-95-2 has been constantly updated, and we look forward to future research findings.
