Using General Procedure F; 1-ethynyl-4-(1-isopropoxycyclopropyl)-benzene (Intermediate 66, 95.0 mg, 0.45 mmol) and methyl-(4-iodophenyl)-acetate (Reagent B, 131.0 mg, 0.45 mmol) in triethylamine (6 mL) was treated with copper(I)iodide (30.0 mg, 0.16 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)palladium(II) (111 mg, 0.16 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-8% EtOAc—hexanes) afforded 110.0 mg (70%) of the title compound as an orange oil.
