Stage #1: With methyllithium In diethyl ether at -78 - -10℃;
Stage #2: With ammonium chloride In diethyl ether
1-(3-Bromo-5-fluorophenyl)-ethanone
Methyllithium (1.3 M in diethyl ether, 35 mL) was added dropwise to 3-bromo-5-fluorobenzoic acid (5 g) in diethyl ether at -78° C. keeping the temperature below -60° C.
The reaction was then left to warm to -10° C. and was stirred for 1 h before being carefully quenched with saturated ammonium chloride (100 mL) until pH=3.
The product was extracted with diethyl ether (2*100 mL), dried over sodium sulfate and the solvent removed by evaporation to yield 1-(3-bromo-5-fluorophenyl)ethanone as an off-white solid (4.67 g, 94percent).

Stage #1: With n-butyllithium In di-isopropyl ether at -78℃; for 0.5 h; Inert atmosphere
Stage #2: at -78 - 30℃; for 0.5 h;
1,3-Dibromo-5-fluoro-benzene (20 g, 78.77 mmol, 1 eq) was dissolved in i-Pr2O (200 mL) in a dried flask under nitrogen. The reaction mixture was cooled to -78 °C and stirred under nitrogen atmosphere. n-BuLi (2.5 M, 31.5 mL, 1 eq) was added drop wise to the above solution and the reaction mixture was stirred at -78 °C for 30 min. After complete addition of n-BuLi, N-methoxy-N-methyl-acetamide (9.75 g, 94.5 mmol, 10.05 mL, 1.2 eq) dropped to the above reaction mixture, while keeping the reaction mixture below -78 °C. After addition, the reaction mixture was warmed slowly to 30 °C for 30 min. The reaction mixture was poured into water (150 mL) and the reaction mixture was stirred for 15 min. The organic phase was separated and the aqueous phase was extracted with ethyl acetate (150 mL), combined organic phase, dried over anhydrous Na2SO4, filtered and evaporated in vacuum to give residue (16 g crude). The residue was purified by flash silica gel chromatography (ISCO®; 120 g CombiFlash® Silica Flash Column, Eluent of 0~10percent Ethyl acetate/Petroleum ether gradient 85 mL/min). Compound was obtained as off-white solid (11.3 g, yield 66percent).1H NMR (400 MHz, CDCl3) δ ppm 7.91 - 7.84 (m, 1H), 7.63 - 7.54 (m, 1H), 7.45 (td, J=2.0, 7.8 Hz, 1H), 2.63 - 2.55 (m, 3H).

YieldReaction ConditionsOperation in experiment
45% With dipyridinium dichromate In dichloromethane at 20℃; for 4 h; To a solution of 1-(3-bromo-5-fluoro-phenyl)-ethanol (2.9 g, 13.2 mmol) in methylene chloride (150 ml) was added at room temperature pyridinium dichromate (3.98 g). The reaction mixture was stirred for 4 hours at room temperature and the solvent was removed in the presence of silica gel. The crude product was purified by chromatography over silica gel to provide 1-(3-bromo-5-fluoro-phenyl)-ethanone (1.39 g, 45percent) as a light yellow solid, MS: m/e=216.1 (M+).
