Procedure

To a solution of ethyl 4-[(5,6-dihydro-5,5-dimethyl-8-(3-pyridyl)-2-naphthalenyl)ethynyl]benzoate (Compound 11) 45.0 mg (0.110 mmol) in 3 ml of EtOH and 2 ml of THF was added 48.0 mg (1.20 mmol, 1.20 ml) of NaOH (1.0 M 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 8.60 (1H, d, J=4.6 Hz), 8.55 (1H, s), 7.90 (2H, d, J=8.3 Hz), 7.76 (1H, d, J=7.5 Hz), 7.60 (2H, d, J=8.3 Hz), 7.51-7.46 (3H, m), 6.94 (1H, s), 6.14 (1H, t, J=4.5 Hz), 2.37 (2H, d, J=4.5 Hz), 1.31 (6H, s).
