Reaction Steps

Using General Procedure D; 4-bromo-1-(1-isopropoxycyclopropyl)-2-ethyl-benzene (Intermediate 93, 300.0 mg, 1.07 mmol) in triethylamine (8 mL) was treated with copper(I)iodide (20.0 mg, 0.11 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) (75.0 mg, 0.11 mmol). The resulting reaction mixture was heated to 70° C. for 5 d. The title compound (320.0 mg, 99%) was isolated by chromatography (0-2% EtOAc-hexanes) as an orange oil.
