Reaction Steps

Following the procedure described for Example 3(A), Step A, N-isopropyl-2-(5-oxo-1-phenyl-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl)-N-phenyl-acetamide (Preparation 7(A)) (411.7 mg, 0.9118 mmol) was alkylated with 3-bromomethyl-indazole-1-carboxylic acid tert-butyl ester (309 mg, 0.993 mmol). Purification by medium pressure chromatography eluting with a solvent gradient (EtOAc to 5% MeOH in EtOAc) provided 391.9 mg 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. 1H NMR (CD3OD) δ 7.99 (m, 2H), 7.22-7.66 (m, 15H), 7.01 (dd, 1H), 4.53-4.81 (m, 3H), 3.88-4.21 (m, 3H), 1.65 (m, 9H), 0.94 (m, 6H).
