実験手順
An ethanol (5.0 ml) suspension of ethyl 2-(4-benzyloxyphenyl)-4,5,6,7-tetramethoxy-2-indancarboxylate (105 mg, 0.213 mmols) and 10% palladium-carbon (32 mg) was stirred under a hydrogen pressure of one atmosphere at room temperature for 4 hours. The palladium-carbon was removed by filtration, and the filtrate was concentrated in vacuo to obtain the entitled compound (81.5 mg) as an oil.
