Product 1

HCID 136352447N-benzyl-2-[8,9-difluoro-4-(1H-indol-3-ylmethylene)-5-oxo-1-phenyl-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl]-N-isopropyl-acetamideYield 75.7%

Procedure

Following the procedure described for Example 1 (A), Step A, N-benzyl-2-(8,9-difluoro-5-oxo-1-phenyl-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl)-N-isopropyl-acetamide (Preparation 9) (200 mg, 0.399 mmol) was condensed over 24 hours with 1H-indole-3-carbaldehyde (70 mg, 0.479 mmol). Purification by medium pressure chromatography eluting with a solvent gradient (CH2Cl2 to 20% acetone in CH2Cl2) provided 190 mg of N-benzyl-2-[8,9-difluoro-4-(1H-indol-3-ylmethylene)-5-oxo-1-phenyl-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl]-N-isopropyl-acetamide. MS 629.3 (M+1), 627.3 (M−1).
