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

实验步骤: A mixture of 2-chloro-5-iodo-benzoic acid methyl ester (3.5 g, 12 mmol), dichlorobis(triphenylphosphino)palladium(II) (0.04 g, 0.06 mmol), triphenylphosphine (0.06 g, 0.24 mmol), copper iodide (0.05 g, 0.24 mmol), (trimethylsilyl)acetylene (1.9 g, 19.2 mmol) in triethylamine (40 mL) was heated at reflux for 12 h. The mixture was concentrated in vacuo, diluted with ethyl acetate (150 mL) and washed sequentially with 10% aqueous citric acid, water, and brine. The organic solution was dried, filtered and concentrated in vacuo to afford the title compound (3.14 g). was heated at reflux for 12 h The mixture was concentrated in vacuo diluted with ethyl acetate (150 mL) washed sequentially with 10% aqueous citric acid, water, and brine The organic solution was dried filtered concentrated in vacuo

实验步骤: A solution of 2-chloro-5-iodo-benzoic acid (25.63 g, 90 mmol) in methanol (500 mL) saturated with HCL gas was stirred at room temperature for 48 h. The reaction mixture was concentrated in vacuo, diluted with 1:1 ethyl acetate/Diethyl ether and washed with saturated aqueous sodium bicarbonate and brine. The organic layer was dried over sodium sulfate, filtered and concentrated in vacuo to afford the title compound (25.0 g). The reaction mixture was concentrated in vacuo diluted with 1:1 ethyl acetate/Diethyl ether washed with saturated aqueous sodium bicarbonate and brine The organic layer was dried over sodium sulfate filtered concentrated in vacuo
