Procedure

To a solution of 3-{6-[(isopropyl-phenyl-carbamoyl)-methyl]-5-oxo-1-phenyl-5,6-dihydro-4H-2,3,6,10b-tetraaza-benzo[e]azulen-4-ylmethyl}-indazole-1-carboxylic acid tert-butyl ester (391.9 mg, 0.674 mmol) in dioxane (8 mL) was added 4M HCl in dioxane (6 mL). The reaction was stirred at room temperature for 24 hours and was diluted with EtOAc. The organic solution was washed with aqueous NaHCO3 and brine, was dried (MgSO4), filtered and concentrated in vacuo. Purification by medium pressure chromatography eluting with a solvent gradient (EtOAc to 10% MeOH in EtOAc) provided 260.9 mg of 2-[4-(1H-indazol-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 (CD3OD) δ 7.90 (d, 1H), 7.65 (d, 2H), 7.34-7.54 (m, 12H), 7.22 (t, 1H), 7.13 (t, 1H), 6.99 (d, 1H), 4.74 (m, 1H), 4.65 (d, 1H), 4.42 (t, 1H), 3.92-4.12 (m, 3H), 0.99 (m, 6H); MS 582.7 (M+1), 580.4 (M−1).
