Procedure

Using General Procedure F; cyclopropyl-ethyl-(4-ethynyl-2-methyl-benzyl)-amine (Intermediate 161, 190.0 mg, 0.89 mmol) and ethyl-4-iodo benzoate (Reagent A, 245.0 mg, 0.89 mmol) in triethylamine (5 mL) was treated with copper(I)iodide (56.0 mg, 0.30 mmol) and sparged with argon for 15 minutes. Dichlorobis(triphenylphosphine)-palladium(II) (208 mg, 0.30 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (3-5% EtOAc-hexanes) afforded the title compound.
