Reaction Steps
Using General Procedure F; 1-ethynyl-4-(1-methoxycyclopropyl)-benzene (Intermediate 61, 100.0 mg, 0.47 mmol) and ethyl-4-iodo benzoate (Reagent A, 141.0 mg, 0.51 mmol) in triethyl amine (6 mL) was treated with copper(I)iodide (30.0 mg, 0.16 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)palladium(II) (109 mg, 0.16 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-5% EtOAc—hexanes) afforded 135.0 mg (90%) of the title compound as an orange solid.
