Adding a certain compound to certain chemical reactions, such as: 29578-39-0, name is 1-Bromo-3-fluoro-5-methoxybenzene, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 29578-39-0, HPLC of Formula: C7H6BrFO
To a solution of Compound 187 (0.700 g, 3.41 mmol) in 1,4-dioxane (5 ml) were added Compound 188 (0.861 g, 4.10 mmol) and PdCl2(dtbpf) (0.223 g, 0.341 mmol), and then 2 mol/L aqueous solution of potassium carbonate (2.561 ml, 5.12 mmol), and the reaction mixture was stirred at 70C. After completion of the reaction, water was added to the reaction mixture, and the resulting mixture was extracted with chloroform, which was then concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography to obtain Compound 189 (0.667 g, 93.8%). Compound 189; Method B LC/MS retention time = 1.99 min. MS (ESI) m/z = 209.35(M+H)+.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1-Bromo-3-fluoro-5-methoxybenzene, and friends who are interested can also refer to it.
