Adding a certain compound to certain chemical reactions, such as: 450-88-4, name is 1-Bromo-4-fluoro-2-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 450-88-4, Recommanded Product: 1-Bromo-4-fluoro-2-methoxybenzene
1-Bromo-4-fluoro-3-methoxybenzene (773 mg, 3.77 mmol) and bis(pinacolato)diboron (1.24 mg, 4.90 mmol) were dissolved in dioxane (10 mL), and anhydrous potassium acetate (1.11 mg, 11.31 mmol) and [1,1′-bis (diphenylphosphino)ferrocene]dichloropalladium.dichloromethane (276 mg, 0.377 mmol) were added. Under nitrogen gas atmosphere, the mixture was heated to 80 C. and stirred for 16 hours. After cooling to room temperature, the mixture was filtered through celite, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel TLC preparative plate (petroleum ether: ethyl acetate=1:1) to give compound 27-a (600 mg, yield 63%). 1H-NMR (400 MHz, CDCl3) delta: 7.65 (t, J=8.0 Hz, 1H), 6.55-6.66 (m, 2H), 3.82 (s, 3H), 1.34 (s, 12H) ppm
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-Bromo-4-fluoro-2-methoxybenzene, other downstream synthetic routes, hurry up and to see.
