Add a 1M solution in tetrahydrofuran of tetrabutylammonium fluoride (37 mL, 37 mmol) to a solution of 3-[(tetrahydro-pyran-2-yloxy)-(4-triisopropylsilanyloxymethyl-phenyl)-methyl]-benzonitrile (14.6 g, 30.4 mmol) in tetrahydrofuran (50 mL) and tetrahydrofuran stir at room temperature for 2 hours. Concentrate the reaction, dilute with water (200 mL), and extract with ethyl acetate (2×100 mL). Combine the extracts, dry over magnesium sulfate, filter, and concentrate. Purify the residue via silica chromatography eluting with 9:1 hexanes:ethyl acetate to 1:1 hexanes ethyl acetate to afford the title compound (8.0 g, 82%), as a colorless thick oil. LCMS (m/z) 323 M+1.
