Into a 10000-mL 4-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed tetrahydrofuran (5000 mL), NH(i-Pr)2 (249 g, 1.20 equiv). This was followed by the addition of n-BuLi (905 mL, 1.10 equiv) dropwise with stirring in 30 min at -70C. The resulting solution was stirred for 0.5 hr at -30C. To this was added 4-bromo-2-fluoro- l-(trifluoromethyl)benzene (500 g, 2.06 mol, 1.00 equiv) dropwise with stirring at -78C in 2 hr. The resulting solution was stirred for 2 hr at -78C. The reaction was then poured into 1000 g of C02(s) at -70C. The pH value of the solution was adjusted to 3 with hydrogen chloride (2N) (1.5 mol/L). The resulting solution was extracted with 3x2000 mL of ethyl acetate and the organic layers combined and dried over anhydrous sodium sulfate and concentrated under vacuum. This resulted in 301 g (50%) of 6-bromo-2-fluoro-3-(trifluoromethyl)benzoic acid as a white solid.
