Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 35277-02-2, name is 4-Fluoro-1H-pyrazole, A new synthetic method of this compound is introduced below., name: 4-Fluoro-1H-pyrazole
4-Fluoro-1H-pyrazole (4.73 g, 55 mmol) and potassium carbonate (17.27 g, 125 mmol) were combined and stirred in N,N-dimethylformamide (41.7 mL) for 10 minutes in an open sealed tube before addition of 2-bromo-5-acetylpyridine (10 g, 50 mmol). The reaction tube was sealed and stirred 20 hours at 100C. The reaction mixture was then cooled to room temperature and poured into water (700 mL). The mixture was sonicated and stirred for 20 minutes. A beige solid was isolated by filtration, washed with small amounts of water, and dried to yield 1-(6-(4-fluoro-1H- pyrazol-1-yl)pyridin-3-yl)ethan-1-one (9.81 g, 96% yield). MS: M+1 = 206.0.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
