실험 절차

Add potassium carbonate (307 mg, 2.22 mmol) to a solution of trimethyl-(3-trifluoromethylphenylethynyl)-silane (1.07 g, 4.42 mmol) in ethanol (15 mL). Stir at room temperature for 16 h. Neutralized with 10% aqueous hydrochloric acid solution. Add water and extract the product with hexanes. Evaporate hexanes slowly in a cool water bath (<15° C.) to give the title compound (580 mg, 77%).
