Participants

Reaction Steps

Using General Procedure F; [1-(4-ethynylphenyl)-cyclopropyl]-propylamine (Intermediate 120, 38.0 mg, 0.19 mmol) and ethyl-4-iodo benzoate (Reagent A, 58.0 mg, 0.21 mmol) in triethyl amine (6 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 (5-15% EtOAc—hexanes) afforded 40.0 mg (61%) of the title compound as an orange oil.
