Using General Procedure F; 1-(4-ethynyl-2-methyl-benzyl)-1H-imidazole (Intermediate 141, 101.0 mg, 0.53 mmol) and methyl-(4-iodophenyl)-acetate (Reagent B, 145.0 mg, 0.53 mmol) in triethylamine (5 mL) was treated with copper(I)iodide (34.0 mg, 0.18 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)palladium(II) (124 mg, 0.18 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (5% MeOH-EtOAc) afforded 45.0 mg (25%) of the title compound as an orange oil.
