The origin of a common compound about 4-Bromo-1-fluoro-2-methoxybenzene

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, 4-Bromo-1-fluoro-2-methoxybenzene, other downstream synthetic routes, hurry up and to see.

Adding a certain compound to certain chemical reactions, such as: 103291-07-2, name is 4-Bromo-1-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 103291-07-2, 103291-07-2

To a solution of 69A (2.7 g, 13.1 mmol) in THF (25 mL) at -78 C. was added n-BuLi (1.6 M in hexanes, 11.0 mL, 17.7 mmol). The mixture was stirred at -78 C. for 40 min before trimethyl borate (2.7 mL, 24.3 mmol) was added. The reaction was left stirring from -78 C. to rt over 18 h. It was quenched with 1.0 N HCl (40 mL), extracted with EtOAc, washed with brine and dried over Na2SO4. After evaporation of the solvent, the crude solid product was triturated with EtOAc/hexanes (1:4). After filtration, 69B (0.75 g, 35% yield) was collected as a white solid. 1H NMR (400 MHz, Methanol-d4) delta ppm 3.86 (s, 3 H) 7.03-7.45 (m, 3 H).
