Procedure

40% Methanolic Triton B (0.12 mL, 0.26 mM) was added to a solution of the 9-[(2-benzylphenyl)methyl]-4-hydroxy-5-carbamoyl carbazole (701 mg, 0.17 mM) in 10 mL DMF at 25° C. After 3 minutes, methyl bromoacetate (55 mg, 0.34 mM) was added and the resultant mixture stirred at room temperature for 25 hours. The mixture was diluted with ethyl acetate, washed with 1 N HCl, 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 60 mg (73%) of the {9-[(2-benzylphenyl)methyl]-5-carbamoylcarbazol-4-yl}oxyacetic acid, methyl ester as a white solid. 1H NMR (CDCl3) δ 7.4-7.00 (m, 14H), 6.65 (d, 1H, J=8 Hz), 6.55 (d, 1H, J=8 Hz), 6.4 (d, 1H, J=8 Hz), 5.4 (s, 2H), 4.95 (s, 2H), 4.2 (s, 2H), and 3.80 (s, 3H).
