Versuchsvorschrift
Following the procedure described for Example 1(A), Step A, 2-[1-(3-hydroxy-phenyl)-5-oxo-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl]-N-isopropyl-N-phenyl-acetamide (Preparation 12) (244 mg, 0.522 mmol) was condensed over 48 hours with 1H-indole-3-carbaldehyde (105 mg, 0.723 mmol). Purification by medium pressure chromatography eluting with a solvent gradient (EtOAc to 5% MeOH in EtOAc to 10% MeOH in EtOAc) yielded 177.9 mg of 2-[1-(3-hydroxy-phenyl)-4-(1H-indol-3-ylmethylene)-5-oxo-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl]-N-isopropyl-N-phenyl-acetamide. 1H NMR (CD3OD) δ 8.23 (d, 1H), 7.90 (s, 1H), 6.90-7.63 (m, 16H), 4.95 (m, 1H), 3.68-4.50 (m, 3H), 1.11 (m, 6H); MS 595.3 (M+1), 593.3 (M−1).
