Procedure

To a solution of ethyl 4-[(5,6-dihydro-5,5-dimethyl-8-(3-((2,2-dimethylethyl)-dimethylsiloxy)-phenyl)-2-naphthalenyl)ethynyl]benzoate (Compound H) 60.0 mg (0.114 mmol) in 1.0 ml of THF at room temperature was added 91.5 mg (0.35 ml, 0.35 mmol) of tetrabutylamonium flouride (1 M solution in THF). After stirring overnight, the solution was diluted with EtOAc and washed with H2O and saturated aqueous NaCl, before being dried over MgSO4. Removal of the solvents under reduced pressure, followed by column chromatography (4:1, Hexanes:EtOAc) afforded the title compound as a colorless solid. 1H NMR (CDCl3): δ 7.98 (2H, d, J=7.8 Hz), 7.52 (2H, d, J=8.3 Hz), 7.39-7.21 (4H, m), 6.93 (1H, d, J=7.5 Hz), 6.84 (1H, d, 7.1 Hz), 6.83 (1H, s), 6.01 1H, t, J=4.7 Hz), 4.91 (1H, s), 4.39 (2H, q, J=7.1 Hz), 2.35 (2H, d, J=4.7 Hz), 1.39 (31, t, J=7.1 Hz), 1.34 (6H, s).
