実験手順

60% Sodium hydride in mineral oil (79.8 mg, 2.0 mM) was added to a solution of 9-[(3-methylphenyl)methyl]-2-methyl-4-hydroxy-5-carbamoyl carbazole (0.55 g, 1.60 mM) in 56 mL DMF and 12 ml THF. After 10 minutes, methyl bromoacetate (0.20 ml, 2.16 mM) was added and the resultant mixture stirred at room temperature for 1 hour. The mixture was diluted with ethyl acetate and washed with H2O. The aqueous layer was extracted with ethyl acetate. The combined organic layers were extracted with saturated brine, dried over sodium sulfate, filtered, and concentrated. The residue was purified by column chromatography on silica gel (elution with methylene chloride/acetone gradient) to afford 0.51 g (76%) of {9-[(3-methylphenyl)methyl]-2-methyl-5-carbamoylcarbazol-4-yl}oxyacetic acid, methyl ester. 1H NMR (DMSO-d6) δ7.5 (m, 2H), 7.35 (dd, J=8 and 8 Hz, 1H), 7.2-7.1 (m, 2H), 7.05-6.95 (m, 4H), 6.85 (d, J=8 Hz, 1H), 6.45 (s, 1H), 5.6 (s, 2H), 4.9 (s, 2H), 3.75 (s, 3H), 2.4 (s, 3H), 2.2 (s, 3H). MS (FD) m/e 400, 417.
