A solution of the 9-[(phenyl)methyl]-2-(4-trifluoromethylphenyl)-4-hydroxy-5-carbomethoxy carbazole (1.10 g, 2.31 mM) in 35 ml THF and 140 mL concentrated aqueous ammonium hydroxide was sonicated for 6 hours at 30-40° C. The precipitated solid was filtered and washed with water. Trituration with Et2O, then with 2:1 Et2O/CH2Cl2 afforded 0.20 g (19%) of the 9-[(phenyl)methyl]-2-(4-trifluoromethylphenyl)-4-hydroxy-5-carbamoyl carbazole. 1H NMR (DMSO-d6) δ 10.8 (s, 1H), 8.9 (bs, 1H), 8.45 (bs, 1H), 8.0 (d, J=8 Hz, 2H), 7.8 (d, J=8 Hz, 2H), 7.6 (s, 1H), 7.5 (m, 2H), 7.3-7.1 (m, 6H), 7.0 (s, 1H), 5.8 (s, 2H).
