실험 절차

Then, 0.04 g of 5% palladium/carbon and 10 ml of a tetrahydrofuran solution containing 0.36 g of 2-(4-decyloxyphenyloxycarbonyl)-1,2,3,4-tetrahydro-6-benzyloxynaphthalene were stirred overnight at room temperature in a stream of hydrogen to decompose a benzyl protective group by hydrogenation. 5% palladium/carbon was removed using Celite as a filter aid, and the filtrate was concentrated. The concentrate obtained was purified by column chromatography to obtain 0.29 g of 2-(4-decyloxyphenyloxycarbonyl)-1,2,3,4-tetrahydro-6-hydroxynaphthalene as a white crystal (isolated yield: 97%).
