Procedure
Using General Procedure F; dibenzyl-[1-(4-ethynylphenyl)-cyclopropyl]-amine (Intermediate 129, 40.0 mg, 0.12 mmol) and ethyl-4-iodo benzoate (Reagent A, 60.0 mg, 0.22 mmol) in triethylamine (5 mL) was treated with copper(I)iodide (8.0 mg, 0.04 mmol) and sparged with argon for 5 minutes. Dichlorobis (triphenylphosphine)palladium(II) (27 mg, 0.04 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-5% EtOAc-hexanes) afforded the title compound as an oil.
