2-Iodoaniline → 2-[4-(tert-Butyldimethylsilanyloxy)but-1-ynyl]phenylamine

참여 물질

반응 단계

2-Iodoaniline (1.76 g, 8 mmol) was dissolved in triethylamine (50 mL) and placed under N2. tert-Butylbut-3-ynyloxydimethylsilane (2.58 g, 14 mmol) was added, followed by bis(triphenylphosphine)palladium(II) chloride (30 mg, 0.042 mmol) and copper(I) iodide (7 mg, 0.036 mmol), and the reaction was stirred overnight at room temperature. Triethylamine was evaporated, and the residue was diluted with ether and filtered through Celite. The filtrate was concentrated, and the residue was purified by SiO2 chromatography (5-20% ethyl acetate/hexanes) to give the desired product. The reaction was assumed to be quantitative.
