Procedure

A solution of the {9-[(2-fluorophenyl)methyl]-5-carbamoylcarbazol-4-yl}oxyacetic acid, methyl ester (47.9 mg, 0.118 mM) and 0.28 mL (0.28 mM) of 1 N NaOH in 10 mL of methanol was sonicated for 6 hours at 50-60° C., then stirred at room temperature for 16 hours. The mixture was diluted with ethyl acetate and acidified to pH 1 with 5 N HCl. The aqueous layer was extracted twice with ethyl acetate. The combined organic extracts were washed with saturated brine, dried over magnesium sulfate, filtered, and concentrated to afford 42.8 mg (92%) of the {9-[(2-fluorophenyl)methyl]-5-carbamoylcarbazol-4-yl}oxyacetic acid as a white powder. 1H NMR (DMSO-d6) δ7.75 (s, 1H), 7.6 (d, 1H, J=8 Hz), 7.5-7.25 (m, 6H), 7.15 (d, 1H, J=8 Hz), 7.05 (dt, 1H, J=1 and 8 Hz), 6.75 (dt, 1H, J=1 and 8 Hz), 6.65 (d, 1H, J=8 Hz), 5.7 (s, 2H), and 4.8 (s, 2H). IR (KBr, cm−1) 3428, 3400, 1737, 1635, 1617, 1583, 1572, 1500, 1491, 1453, 1434, 1330, 1248, 1158, 1098, 760, and 714. MS (FD) m/e 392.
