A solution of 9-[(3-methylphenyl)methyl]-2-methyl-4-hydroxy-5-carbomethoxy carbazole (0.92 g, 2.56 mM) in 38 ml THF and 154 mL concentrated aqueous ammonium hydroxide was sonicated for 6 h at 30-40° C. The precipitated solid was filtered, washed with water to afford 0.55 g (63%) of 9-[(3-methylphenyl)methyl]-2-methyl-4-hydroxy-5-carbamoyl carbazole. 1H NMR (DMSO-d6) δ10.5 (s, 1H), 8.8 (bs, 1H), 8.4 (bs, 1H), 7.75 (m, 1H), 7.4 (m, 2H), 7.15 (dd, J=8 and 8 Hz, 1H), 7.05 (m, 1H), 7.0 (s, 1H), 6.9 (s, 1H), 6.8 (d, J=8 Hz, 1H), 6.45 (s, 1H), 5.65 (s, 2H), 2.4 (s, 3H)., 2.2 (s, 3H).
