실험 절차

Employing the same general procedure as for the preparation of ethyl 4-[(7,8-dihydro-8,8-dimethyl-5-ethylthionaphth-3-yl)ethynyl]benzoate (Compound 151), 500 mg (1.44 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 (colorless crystals, recrystallized from methyl alcohol) using 268 mg (1.42 mmol) of titanium tetrachloride, 184 mg (1.49 mmol) of benzyl mercaptan and 271 mg (2.82 mmol) of triethylamine.
