A suspension of the {9-[(3-trifluoromethoxyphenyl)methyl]-5-carbamoylcarbazol-4-yl}oxyacetic acid, methyl ester (22.4 mg, 0.047 mM) and 0.065 mL (0.065 mM) of 1 N NaOH in 5 mL of ethanol was stirred for 24 hours at 25° C. The solvent was removed in vacuo and the residue suspended in EtOH. The resultant white precipitate was collected by filtration, washed with a small amount of EtOH, then dried in vacuo to afford 9 mg (41%) of the {9-[(3-trifluoromethoxyphenyl)methyl]-5-carbamoylcarbazol-4-yl}oxyacetic acid, sodium salt as a white powder. MS (ES) m/e 457, 459.
