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. 25016-12-0, name is 1,3-Dimethyl-1H-pyrazole-4-carbaldehyde belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. COA of Formula: C6H8N2O
6.22. Synthesis of (S)-2-Amino-3-(4-(5-((1,3-dimethyl-1H-pyrazol-4-yl)methylamino)pyrazin-2-yl)phenyl)propanoic acid A mixture of 1,3-dimethyl-1H-pyrazole-4-carbaldehyde (142 mg, 1.145 mmol), 2-amino-5-bromopyrazine (200 mg, 1.149 mmol), borane trimethylamine complex (126 mg, 1.73mmol) and glacial acetic acid (137 mg, 2.29 mmol) in anhydrous methonol (3 ml) was stirred at room temperature overnight. The reaction mixture was then diluted with ethyl acetate, washed with water, dried over MgSO4 and filtered. The filtrate was concentrated to give 300 mg of (5-bromo-pyrazin-2-yl)-(1,3-dimethyl-1H-pyrazol-4-ylmethyl)amine as crude product, which was used for next step reaction without further purification. Crude yield: 93%.
The synthetic route of 25016-12-0 has been constantly updated, and we look forward to future research findings.
