6-Ethynyl-7-methoxy-1,1-dimethyl-3,4-dihydro-1H-naphthalen-2-one (346 mg) was dissolved in ethanol:THF (=2:1 mixture solvent, 20 ml), added with 10% Pd/C (170 mg), and then the mixture was stirred at room temperature for 1 hr under hydrogen atmosphere. The catalyst was removed by filtration and the organic layer was concentrated under reduced pressure to obtain the title compound (322 mg, yield 91%).
