Procedure

To a solution of 46.5 mg (0.098 mmol) ethyl 2-fluoro-4-[[(5,6-dihydro-5,5-dimethyl-8-(4-methylphenyl)-2-naphthalenyl)thiocarbonyl]amino]-benzoate (Compound 62) in 1.0 ml EtOH and 1.0 ml of THF was added 55 mg NaOH (1.4 mmol) and 1.0 ml of H2O. After stirring at room temperature for overnight EtOAc was added, and the reaction quenched by the addition of 10% HCl. Extraction with EtOAc was followed by washing of the combined organic layers with H2O, saturated aqueous NaCl, and drying over MgSO4. Removal of the solvent under reduced pressure provided a solid which after crystallization from CH3CN afforded the title compound as a pale-yellow solid. 1H NMR (d6 -acetone): δ 11.05 (1H, s), 8.02 (1H, m), 7.99 (1H, t, J=8.3 Hz), 7.75 (1H, m), 7.69 (1H, dd, J=2.0, 6.1 Hz), 7.52 (1H, s), 7.46 (1H, d, J=8.1 Hz), 7.21 (4H, m), 6.04 (1H, t, J=4.8 Hz), 2.37 (2H, d, J=4.8 Hz), 2.33 (3H, s), 1.36 (6H, s).
