Versuchsvorschrift
Using General Procedure F; 1-ethynyl-4-(1-benzyloxycyclopropyl)-3-ethyl-benzene (Intermediate 90, 90.0 mg, 0.33 mmol) and ethyl-4-iodo benzoate (Reagent A, 100.0 mg, 0.36 mmol) in triethylamine (5 mL) was treated with copper(I)iodide (21.0 mg, 0.11 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)palladium(II) (77 mg, 0.11 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-4% EtOAc-hexanes) afforded 100.0 mg (72%) of the title compound.
