実験手順
Employing the same general procedure as for the preparation of 4-[(5,6,7,8-tetrahydro-8,8-dimethyl-5-oxonaphth-2-yl) ethynyl]benzoic acid (Compound 7), 500 mg (1.45 mmol) of ethyl 4-[(5,6,7,8-tetrahydro-8,8-dimethyl-5-oxonaphth-3-yl)ethynyl]benzoate (Compound 2) was converted into the title compound using 4 ml (4 mmol) of LiOH (1 N aqueous solution).
