실험 절차
A solution of the 9-[(1-naphthyl)methyl]-4-hydroxy-5-carbomethoxy carbazole (210 mg, 0.55 mM) in 10 mL THF and 30 mL concentrated aqueous ammonium hydroxide was sonicated for 20 hours at 40-50° C. The mixture was diluted with ethyl acetate and acidified to pH 1 with 5 N HCl. The aqueous layer was extracted three times with ethyl acetate. The combined organic extracts were washed with saturated brine, dried over magnesium sulfate, filtered, and concentrated. The residue was purified by column chromatography on silica gel (elution with gradient hexanes/ethyl acetate) to afford 80 mg (40%) of the 9-[(1-naphthyl)methyl]-4-hydroxy-5-carbamoyl carbazole as a white solid. 1H NMR (DMSO-d6) δ 10.55 (s, 1H), 8.8 (br s, 1H), 8.4 (br s, 1H), 8.35 (d, 1H, J=8 Hz), 7.95 (d, 1H, J=8 Hz), 7.8 (d, 1H, J=8 Hz), 7.65 (m, 4H), 7.45 (m, 2H), 7.25 (t, 1H, J=8 Hz), 7.15 (t, 1H, J=8 Hz), 6.9 (d, 1H, J=8 Hz), 6.6 (d, 1H, J=8 Hz), and 6.2 (s, 2H). MS (ES) m/e 365, 367.
