Reaction Steps

1-(4-Hydroxy-phenyl)-2-phenyl-1H-indole-3-carbonitrile (Example 46, 10 mg, 0.03 mmol) was dissolved in 1 ml of MeOH. H2O2 (1 ml, 35% by weight in H2O) and 2M KOH (0.5 ml) were added and the reaction mixture was heated to reflux over night. The mixture was acidified with 1M HCl and EtOAc was added. The phases were separated and the organic solvents were evaporated. The crude product was purified by reversed phase preparative HPLC to give the title amide. ES/MS m/z: 329.1 (M+H), 327.13 (M−H); 1H NMR (acetone-d6, 500 MHz): 8.34 (m, 1H), 7.46 (m, 2H), 7.40-7.37 (m, 3H), 7.24-7.18 (m, 2H), 7.12 (m, 2H), 7.07 (m, 1H) and 6.85 (m, 2H).
