Reaction Steps
A mixture of 5-chloro-2-fluoroiodobenzene (5.00 g), copper(I) iodide (74.3 mg), triphenylphosphine (256 mg), tris(dibenzylideneacetone)dipalladium(0) chloroform adduct (404 mg), propargyl alcohol (1.27 ml), diisopropylethylamine (13.6 ml) and tetrahydrofuran (100 ml) was stirred at room temperature for 8 hr. The reaction mixture was added to brine, and the mixture was extracted with ethyl acetate, washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=99:1-80:20) to give the object product (2.82 g) as a brown oil.
