HCID 1363524432-[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-(6-methoxy-pyridin-3-yl)-acetamideYield 77.2%

Procedure

Following the procedure described for Example 1(A), Step A, N-isopropyl-N-(6-methoxy-pyridin-3-yl)-2-(5-oxo-1-phenyl-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl)-acetamide (Preparation 11) (293 mg, 0.608 mmol) was condensed with 1H-indole-3-carbaldehyde (106 mg, 0.729 mmol). Purification by medium pressure chromatography eluting with a solvent gradient (2% MeOH in CH2Cl2 to 10% MeOH in CH2Cl2) yielded 286 mg of 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-(6-methoxy-pyridin-3-yl)-acetamide. 1H NMR (CD3OD) δ 8.25 (s) and 7.90 (s, total 1H), 8.16 (s, 1H), 7.58-7.67 (m, 4H), 7.37-7.53 (m, 6H), 7.07-7.17 (m, 3H), 6.94 (m, 2H), 4.90 (m, 1H), 4.55 (m, 1H), 4.25 (m, 1H), 3.96 (m, 4H), 1.10 (m, 6H); MS 610.8 (M+1), 608.5 (M−1)
