Versuchsvorschrift

To a solution of 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)) (1.2 g, 2.7 mmol) in toluene (15 mL) was added 1H-indole-3-carbaldehyde (0.46 g, 3.2 mmol) and piperidine (0.4 mL). The reaction mixture was heated to reflux for 14 hours. Activated 4 Å molecular sieves (2 g) were added and the reaction mixture was refluxed for 24 hours. The sieves were removed by filtration and the filtrate was concentrated. The residue was triturated with methylene chloride and the solid was collected via filtration and was dried in vacuo to give 1.5 g 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-phenyl-acetamide. The filtrate was concentrated and was purified by chromatography (20% acetone/methylene chloride) to afford an additional 320 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-phenyl-acetamide. MS 579.2 (M+1).
