To 10% Pd/C and EtOH was added 2-[4-(1H-indol-3-ylmethylene)-5-oxo-1-phenyl-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl]-N-isopropyl-N-phenyl-acetamide (0.71 g, 1.2 mmol). An additional 25 mL of EtOH was added followed by ammonium formate (0.77 g, 12.2 mmol). The reaction mixture was heated to 80° C. for 6 hours. The catalyst was removed by filtration through Celite® and the filtrate was concentrated. The residue was dissolved in ethyl acetate and the organic solution was washed with saturated NaHCO3. The organic phase was dried over sodium sulfate and concentrated. The crude product was purified by chromatography (0% to 18% acetone/methylene chloride) to give 128 mg of 2-[4-(1H-indol-3-ylmethyl)-5-oxo-1-phenyl-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl]-N-isopropyl-N-phenyl-acetamide as a racemic mixture. 1H NMR (CD2Cl2) δ 8.18 (s, 1H), 7.64 (dd, 2H), 7.55 (dd, 1H), 7.510-7.41 (m, 8H), 7.36 (dd, 1H), 7.25 (m, 3H), 7.09 (m, 2H), 7.027 (m, 1H), 6.85 (dd, 1H), 4.86 (m, 1H), 4.40 (br d, 1H), 4.04 (dd, 1H), 3.79 (m, 3H), 1.03 (dd, 6H); MS 581.4 (M+1).
