Procedure

To a solution of ethyl 4-[(5,6-dihydro-5,5-dimethyl-8-(4-trifluoromethylphenyl)-2-naphthalenyl)ethynyl]benzoate (Compound 9) 70.0 mg (0.148 mmol) in 3 ml of EtOH and 2 ml of THF was added 60.0 mg (1.50 mmol, 1.50 ml) of NaOH (1.0M aqueous solution). The solution was heated to 50° C. for 2 hours, cooled to room temperature, and acidified with 10% HCl. Extraction with EtOAc, followed by drying over Na2SO4, and removal of the solvents under reduced pressure afforded the title compound as a colorless solid. 1H NMR (DMSO): δ 7.90 (2H, d, J=8.3 Hz), 7.80 (2H, d, J=8.1 Hz), 7.61-7.47 (6H, m), 6.97 (2H, s), 6.16 (1H, t, J=4.5 Hz), 2.37 (2H, d, J=4.6 Hz), 1.30 (6H, s).
