Employing the same general procedure as for the preparation of 4-[(7,8-dihydro-8,8-dimethyl-5-(1,1-dimethylethyl)naphth-3-yl )ethynyl]benzoic acid (Compound 80), 42.0 mg (0.106 mmol) of ethyl 4-[(7,8-dihydro-8,8-dimethyl-5-(1-pentynyl)naphth-3-yl)ethynyl]benzoate (Compound 75) was converted into the title compound (colorless solid) using 11.1 mg (0.27 mmol) of LiOH in H2O in 3 mL of THF/water (3:1, v/v, flushed with argon).
