Reaction Steps
To a solution of ethyl 4-[(5,6-dihydro-5,5-dimethyl-8-(4-methoxyphenyl)-2-naphthalenyl)ethynyl]benzoate (Compound 8) 80.0 mg (0.183 miol) in 3 ml of EtOH and 2 ml of THF was added 40.0 mg (1.00 mmol, 1.0 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 7.90 (2H, d, J=8.3 Hz), 7.60 (2H, d, J=8.3 Hz), 7.45 (2H, s), 7.24 (2H, d, J=8.6 Hz), 7.02-6.89 (3H, m), 5.98 (1H, t, J=4.4 Hz), 3.79 (3H, s), 2.31 (2H, d, J=4.7 Hz), 1.29 (6H, s).
