Using General Procedure D; 4-bromo-1-(1-isopropoxycyclopropyl)-2-methyl-benzene (Intermediate 79, 250.0 mg, 0.95 mmol) in triethylamine (8 mL) was treated with copper(I)iodide (19.0 mg, 0.10 mmol) and then sparged with argon for 5 minutes. Trimethylsilylacetylene (0.70 g, 7.1 mmols) was then added followed by dichlorobis-(triphenylphosphine)palladium(II) (70.0 mg, 0.1 mmol). The resulting reaction mixture was heated to 70° C. for 5d. The title compound (250.0 mg, 91%) was isolated by chromatography (0-3% EtOAc-hexanes).
