Participants

Reaction Steps

A solution of 110.0 mg (0.213 mmol). 2-trimethylsilylethyl 4[[(5,6-dihydro-5,5-dimethyl-8-(4-methylphenyl)-2-naphthalenyl)carbonyl]oxy]-benzoate (Compound 38) and 167.3 mg of tetrabutylammonium flouride (0.640 mmol, 0.64 ml of a 1M solution in THF) in 2.0 ml THF was stirred at room temperature for 22 hours. Ethyl acetate was added and the resulting solution washed with H2O and saturated aqueous NaCl then dried over MgSO4. Removal of the solvents under reduced pressure and washing of the residual solid with EtOAc and CH3CN afforded the title compound as a colorless solid. 1H NMR (d6-acetone): δ 8.10 (2H, d, J=8.8 Hz), 8.06 (1H, dd, J=2.0, 8.1 Hz), 7.82 (1H, d, J=1.9 Hz), 7.64 (1H, d, J=8.1 Hz), 7.35 (2H, d, J=8.6 Hz), 7.25 (4H, m), 6.08 (1H, t, J=4.7 Hz), 2.42 (2H, d, J=4.7 Hz), 2.35 (3H, s), 1.39 (6H, s).
