Procedure
A suspension of the {9-[(2-cyanophenyl)methyl]-5-carbamoylcarbazol-4-yl}oxyacetic acid, methyl ester (110 mg, 0.266 mM) and 0.29 mL (0.29 mM) of 1 N NaOH in 5 mL of ethanol was sonicated for 2 hours at 25° C. The resultant white precipitate was collected by filtration, washed with small amounts of EtOH, diethyl ether, and hexanes, then dried in vacuo to afford 107 mg (95%) of the {9-[(2-cyanophenyl)methyl]-5-carbamoylcarbazol-4-yl}oxyacetic acid, sodium salt as a white powder. 1H NMR (DMSO-d6) δ7.9 (d, 1H, J=8 Hz), 7.6 (br s, 1H), 7.5 (d, 1H, J=8 Hz), 7.45-7.4 (m, 3H), 7.35 (t, 1H, J=8 Hz), 7.25 (t, 1H, J=8 Hz), 7.1 (d, 1H, J=8 Hz), 7.05 (d, 1H, J=8 Hz), 6.55 (d, 1H, J=8 Hz), 6.4 (d, 1H, J=8 Hz), 5.8 (s, 2H), and 4.3 (s, 2H). IR (KBr, cm−1) 2220, 1652, and 1613. MS (ES) m/e 398, 400.
