HCID 24350Copper(1+) iodide; Copper(I) iodide; Cuprous iodide; Cuprous iodide (CuI)Catalyst

Procedure

N-Propargylpyrazole (130 mg, 1.23 mmol) and diisopropylamine (0.40 mL, 2.85 mmol) were added to a solution of methyl (Z)-[4-[3-(4-tert-butylphenyl)-3-(4-iodophenyl)allyloxy]-2-methylphenoxy]cetate (350 mg, 0.614 mmol; prepared as described in example 30) in tetrahydrofuran (10 mL). The mixture was degassed and copper(I) iodide (10 mg, 0.053 mmol) and bis(triphenylphosphine)alladium(II) dichloride (22 mg, 0.031 mmol) were added. The reaction mixture was stirred at ambient temperature over night, filtered and the filtrate was evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 4:1-3:1) yielding methyl (Z)-[4-[3-(4-tert-butyl-phenyl)-3-[4-[3-(pyrazol-1-yl)propynyl]phenyl]allyloxy]-2-methylphenoxy]acetate as brown oil.
