Reaction Steps

Using General Procedure F; 1-(1-ethoxycyclopropyl)-4-ethynyl-2-tert-butylbenzene (Intermediate 112, 70.0 mg, 0.30 mmol) and ethyl-4-iodo benzoate (Reagent A, 85.0 mg, 0.30 mmol) in triethylamine (5 mL) was treated with copper(I)iodide (19.0 mg, 0.01 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)-palladium(II) (70 mg, 0.01 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (1-2% EtOAc-hexanes) afforded 70.0 mg (73%) of the title compound.
