실험 절차

5-(Tert-butyl-dimethyl-silyloxy)-2-(7-(tert-butyl-dimethyl-silyloxy)-4-{1-hydroxy-1-[4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-ethyl}-2H-chromen-3-yl)phenol, prepared as in STEP A above, was dissolved in toluene (8 mL) and treated with diluted HCl (0.4 mL of concentrated HCl:H2O=1:2 v/v). The reaction mixture was vigorously stirred at room temperature for 1.5 h. The mixture was then diluted with water and ethyl acetate. The layers were separated and the organic layer washed successively with saturated NaHCO3, brine and dried over MgSO4. The desiccant was filtered off, and the filtrate concentrated. Flash chromatography with ethyl acetate:hexane:CH3OH (containing 1% NH4OH)=49:49:2 as the eluent to yield the title compound as a light oil.
