Using General Procedure F; 1-(1-ethoxycyclopropyl)-4-ethynyl-2-isopropylbenzene (Intermediate 103, 120.0 mg, 0.52 mmol) and methyl-(4-iodophenyl)-acetate (Reagent B, 150.0 mg, 0.52 mmol) in triethylamine (8 mL) was treated with copper(I)iodide (32.0 mg, 0.17 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)palladium(II) (121 mg, 0.17 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-5% EtOAc-hexanes) afforded 140.0 mg (71%) of the title compound as a pale-yellow oil.
