Using General Procedure F; 1-ethynyl-4-(1-benzyloxycyclopropyl)-3-ethyl-benzene (Intermediate 90, 107.0 mg, 0.39 mmol) and methyl-(4-iodophenyl)-acetate (Reagent B, 110.0 mg, 0.39 mmol) in triethylamine (5 mL) was treated with copper(I)iodide (25.0 mg, 0.13 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)palladium(II) (91 mg, 0.13 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-4% EtOAc-hexanes) afforded 130.0 mg (79%) of the title compound as a pale-yellow oil.
