To a solution of 3,5-dibromobenzoic acid (2.5 g, 8.9 mmol) in Et2O (30 mL) at 0° C. was added methyl lithium (1.6M in diethyl ether; 12.3 mL, 19.6 mmol) was added dropwise. The reaction was warmed to room temperature and stirred for 2 hours. Acidic work-up, followed by silica gel chromatography, gave 1-(3,5-dibromo-phenyl)-ethanone.
