실험 절차

N-[1-(1,2,2a,3,4,5-Hexahydroacenaphthylen-1-yl)piperidin-4-yl]-benzene-1,2-diamine (1.15 g) was dissolved in THF (70 ml), 1,1′-carbonyldiimidazole (0.591 g) was added, and the mixture was stirred at room temperature for 3 hr. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated aqueous ammonium chloride solution, dried over magnesium sulfate, and concentrated. The obtained residue was purified by silica gel column chromatography (chloroform/methanol) to give the title compound (0.76 g) as a white solid.
