Procedure

Using General Procedure F; benzyl-[1-(4-ethynylphenyl)-cyclopropyl]-methylamine (Intermediate 132, 70.0 mg, 0.28 mmol) and ethyl-4-iodo benzoate (Reagent A, 77.0 mg, 0.28 mmol) in triethylamine (5 mL) was treated with copper(I)iodide (18.0 mg, 0.10 mmol) and sparged with argon for 5 minutes. Dichlorobis (triphenylphosphine)palladium(II) (65 mg, 0.10 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-5% EtOAc-hexanes) afforded 86 mg (75%) of the title compound as an oil.
