실험 절차

40% Methanolic Triton B (0.15 mL, 0.34 mM) was added to a solution of the 9-[(3-trifluoromethoxyphenyl)methyl]-4-hydroxy-5-carbamoyl carbazole (115 mg, 0.28 mM) in 8 mL DMF at room temperature. After 3 minutes, methyl bromoacetate (65 mg, 0.41 mM) was added and the resultant mixture stirred at room temperature for 23 hours. The mixture was diluted with ethyl acetate, washed with H2O, and saturated brine, dried over magnesium sulfate, filtered, and concentrated. The residue was purified by column chromatography on silica gel (elution with ethyl acetate) to afford 112 mg (83%) of the {9-[(3-trifluoromethoxyphenyl)methyl]-5-carbamoylcarbazol-4-yl}oxyacetic acid, methyl ester as a white solid. 1H NMR (DMSO-d6) δ7.6 (d, 1H, J=8 Hz), 7.55 (br s, 1H), 7.5-7.0 (m, 9H), 6.6 (d, 1H, J=8 Hz), 5.7 (s, 2H), 4.9 (s, 2H), and 3.75 (s, 3H).
