Procedure

To a solution of 26.5 mg (0.06 mmol) ethyl 4[[(5,6-dihydro-5,5-dimethyl-8-(4-methylphenyl)-2-naphthalenyl)carbonyl]amino]-benzoate (Compound 35) in 3.0 ml EtOH and 4.0 ml of THF was added 240.1 mg NaOH (6.00 mmol, 3.0 ml of a 2M aqueous solution). After stirring at room temperature for 72 hours, the reaction was quenched by the addition of 10% HCl. Extraction with EtOAc, and drying of the organic layers over MgSO4, provided a solid after removal of the solvent under reduced pressure. Crystallization from CH3CN afforded the title compound as a colorless solid. 1H NMR (d6-DMSO): δ 10.4 (1H, s), 7.91-7.81 (5H, m), 7.54 (1H, d, J=8.1 Hz), 7.45 (1H, d, J=1.7 Hz), 7.23 (4H, s), 6.04 (1H, t, J=4.7 Hz), 2.35 (5H, s), 1.33 (6H, s).
