Synthetic Route of 35277-02-2<\/a>, 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. 35277-02-2, name is 4-Fluoro-1H-pyrazole belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.<\/p>\n

Step 1: Synthesis of 5-(4-fluoro-lH-pyrazol-l-yl)pyrazine-2-carbonitrile. (0362) To a solution of 5-chloropyrazine-2-carbonitrile (280 mg, 2.0 mmol) in DMF was added 4-fluoro-lH-pyrazole (170 mg, 2.0 mmol) and potassium acetate (395 mg, 4.0 mmol). The mixture was stirred at 100 C for 4 hours, then cooled to 20 C, poured into brine (25 mL), and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, concentrated, and purified by column chromatography (hexane: ethyl acetate = 5: 1) to give 5-(4-fluoro-lH- pyrazol-l-yl)pyrazine-2-carbonitrile (310 mg, 82%). The structure was confirmed by LC-MS.<\/p>\n

The synthetic route of 4-Fluoro-1H-pyrazole has been constantly updated, and we look forward to future research findings.<\/p>\n
