反应条件: temp:0.00; pressure:0.00; stir:

反应条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 3,5-dibromobenzoic acid (2.5 g, 8.9 mmol) in Et2O (30 mL) at 0° C. was added methyllithium (1.6M in Et2O; 12.3 mL, 19.6 mmol) dropwise. The reaction was stirred at 0° C. for 2 hours, and then worked-up with EtOAc and 10% aqueous HCl. The crude material was purified by silica gel chromatography to give the title compound. The crude material was purified by silica gel chromatography

实验步骤: 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. was added dropwise
