Using General Procedure D; 4-(1-ethoxycyclopropyl)-3-tert-butyl phenyl 1,1,1-trifluoromethansulfonate (Intermediate 110, 260.0 mg, 0.71 mmol) in triethylamine (4 mL) and DMF (6 mL) was sparged with argon for 5 minutes. Trimethylsilylacetylene (0.70 g, 7.1 mmols) was then added followed by dichlorobis-(triphenylphosphine)palladium(II) (40.0 mg, 0.06 mmol). The resulting reaction mixture was heated to 95° C. for 18 hours. The title compound, 215.0 mg (96%), was isolated by chromatography (0-2% EtOAc-hexanes) as an orange oil.
