참여 물질

반응 단계

A solution of 3-[methoxy-(4-triisopropylsilanyloxymethyl-phenyl)-methyl]-benzonitrile (0.4 g, 0.976 mmol), tetrahydrofuran (10 mL) and a 1M tetrahydrofuran solution of tetrabutylammonium fluoride (1.2 mL, 1.2 mmol) is stirred at room temperature 18 hr. The mixture is diluted with water (100 mL) and extracted with ethyl acetate (2×50 mL) and the combined extracts are concentrated. The residue is purified via silica chromatography eluting with hexanes to 1:1 hexanes:ethyl acetate to give the title compound (188 mg, 76%) as a colorless oil. LCMS M+1 254.
