Using General Procedure D; 3-isopropyl-4-(1-methyl-cyclopropoxymethyl)-phenyl 1,1,1-trifluoromethanesulfonate (Intermediate 164, 120.0 mg, 0.34 mmol) in triethylamine (2 mL) and anhydrous DMF (5 mL) was sparged with argon for 5 minutes. Trimethylsilyl acetylene (700.0 mg, 0.71 mmol) was then added followed by dichlorobis(triphenylphosphine)palladium(II) (24.0 mg, 0.03 mmol). The resulting reaction mixture was heated to 95° C. for 60 hours. The title compound 110.0 mg, (99%) was isolated by chromatography (0-1% EtOAc-hexanes).
