1,3-Dibromo-2-chloro-5-fluorobenzene Use and Manufacturing
l, 3-Dibromo-2-chloro-5-fluorobenzene (400 mg, 1.39 mmol) dissolved in toluene (4 mL) and 2- methyltetrahydrofuran (1 mL) was treated with the triisopropyl borate (390 pL, 1.69 mmol). The mixture was cooled to -78 C in a dry ice/acetone bath and then n-butyllithium (2.5 M in hexanes, 680 pL, 1.70 mmol) was added slowly dropwise. The mixture was maintained at -78 C for 1 h and then slowly allowed to warm to room temperature. After stirring for 1 h, the reaction mixture was quenched by adding 1N HC1 solution, diluted with ethyl acetate and washed with water and brine. The organic layer was dried over sodium sulfate and filtered. The filtrate was concentrated and purified by ISCO silica gel chromatography to give (3-bromo-2-chloro-5-fluorophenyl)boronic acid.To 150 mL of DMF (dimethylformaldehyde), DMF (dimethylformaldehyde)To a solution of
