실험 절차

To a solution of 6-methoxy-2-(4-methoxy-2-nitrophenyl)-1,1-dimethyl-1,4-dihydronaphthalene (433 mg) in tetrahydrofuran (6 ml) and methanol (6 ml) was added 10% palladium-activated charcoal (200 mg), and the solution was stirred for 3.5 hours at room temperature under a hydrogen atmosphere at 4 atmospheric pressures. After filtration through celite pad, the solvent was evaporated in vacuo, and the resulting solid was washed with hexane-diethyl ether system to provide the title compound (314 mg).
