Using General Procedure D; 1-(4-bromo-2-methyl-benzyl)-1H-imidazole (Intermediate 139, 160.0 mg, 0.64 mmol) in triethylamine (8 mL) was treated with copper(I)iodide (12.0 mg, 0.07 mmol) and then sparged with argon for 5 minutes. Trimethylsilyl acetylene (0.70 g, 0.71 mmols) was then added followed by dichlorobis(triphenylphosphine)palladium(II) (45.0 mg, 0.07 mmol). The resulting reaction mixture was heated to 70° C. for 5 days. The title compound (140.0 mg, 82%) was isolated by chromatography (5% MeOH-EtOAc) as an orange oil.
