A mixture of trifluoromethanesulfonic acid 3-fluoro-2-nitrophenyl ester (149 mg, 0.52 mmol), dichlorobis(triphenylphosphine)palladium (II) (20 mg, 0.028 mmol), copper (I) iodide (14 mg, 0.074 mmol), tetrabutyl ammonium iodide (200 mg, 0.54 mmol), 0.25 mL of anhydrous triethylamine, 0.5 mL of anhydrous acetonitrile, and 0.5 mL of anhydrous tetrahydrofuran was stirred at room temperature for 30 minutes. The resulting mixture was treated with 6-(5-fluoro-2-methylphenyl)-6-methyl-4-trifluoromethylhept-1-yn-4-ol (145 mg, 0.48 mmol) and stirred at room temperature for 18 hours. The crude product was purified by chromatography on SiO2 (50% hexanes in dichloromethane) to give 96 mg of the title product as light yellow oil, (45% yield).
