Procedure
2-(5,6-Dichloro-1H-benzoimidazol-2-yl)-1,1,1-trifluoro-pent-4-yn-2-ol (0.27 g; 0.83 mmol), iodobenzene (0.14 mL; 1.3 mmol), dichlorobis(triphenylphosphine)palladium (31.7 mg; 0.045 mmol), copper iodide (17.8 mg; 0.093 mmol) and triethylamine (0.25 mL; 1.8 mmol) were suspended in THF (5 mL) and the resulting mixture stirred vigorously overnight. The reaction mixture was then concentrated in vacuo and the resulting crude brown oil was purified by column chromatography (SiO2; 50% ether/CH2Cl2) to yield the title compound as an orange-yellow solid.
