실험 절차

To a solution of 3-bromo-5-(trifluoromethyl)-2-((trimethylsilyl)ethynyl)aniline (2.70 g) in methanol (30 mL) was added potassium carbonate (1.11 g), and the mixture was stirred overnight at room temperature. The solvent was evaporated under reduced pressure, to the residue was added saturated aqueous ammonium chloride solution, and the mixture was extracted with ethyl acetate. The extract was washed with saturated aqueous ammonium chloride solution and saturated brine, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (1.56 g).
