Procedure

Using General Procedure F; 1-ethynyl-4-(1-isopropoxycyclopropyl)-3-ethyl-benzene (Intermediate 95, 130.0 mg, 0.57 mmol) and methyl-(4-iodophenyl)-acetate (Reagent B, 157.0 mg, 0.57 mmol) in triethylamine (5 mL) was treated with copper(I)iodide (36.0 mg, 0.19 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)palladium(II) (133 mg, 0.19 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-5% EtOAc-hexanes) afforded 150.0 mg (70%) of the title compound as an orange oil.
