실험 절차
Employing the same general procedure as for the preparation of 4-[(7,8-dihydro-8,8-dimethyl-5-phenylnaphth-2-yl)ethynyl]benzoic acid (Compound 97), 75 mg (0.20 mmol) of ethyl 4-[(7,8-dihydro-8,8-dimethyl-5-(1-propynyl)naphth-2-yl)ethynyl]benzoate (Compound 92) was converted to the title compound (pale yellow solid) using 42 mg (2 ml, 1.0 mmol) of LiOH (0.5 M aqueous solution).
