실험 절차
4-t-Butyldimethylsilyoxy-2-phenylindole (55 mg, 0.17 mmol) was dissolved in THF (10 ml) at 0° C. and treated with tetrabutylammonium flouride (0.5 ml, 1.0 M in THF, excess). After stirring at this temperature for 10 minutes, the reaction was quenched by addition of saturated ammonium chloride. The mixture was extracted several time with ethyl acetate, dried over magnesium sulfate, and evaporated to give a crude oil. Flash chromatography (5% ethyl acetate/hexanes) provided the desired phenol (30 mg, 84.8%) as a white solid. NMR. MS.
