4-Nitrophenol → 2-(4-Nitrophenoxy)ethanol

참여 물질

반응 단계

A mixture of p-nitrophenol (1.39 g, 10 mmol), 2-chloroethoxytrimethylsilane (3.2 ml, 20 mmol), potassium carbonate (4.15 g, 30 mmol), cesium carbonate (163 mg, 0.5 mmol), and sodium iodide (149 mg, 1 mmol) in N,N-dimethylformamide (10 ml) is heated at 75° for 19.5 hours. After cooling to ambient temperature, the mixture is diluted with ethyl acetate and filtered. The filtrate is washed with saturated aqueous sodium bicarbonate, then washed 2× with water, dried over magnesium sulfate, filtered, concentrated in vacuo, and purified on Silica gel (1:1 ethyl acetate/hexanes) to give 4-nitro-(2-Hydroxyethoxy)benzene (1.25 g).
