3-Azido-2-phenylindan-1-one (4), which was obtained from 3-chloro-2-phenylindan-1-one (3), cyclizes on thermolysis to 5H-indeno[1,2-b]indol-10-one (5). Reaction of 3-azido-2-phenylindan-1-one (4) with triphenylphosphane gives 2-phenyl-3-(triphenylphosphoranylideneamino)-indan-1-one (6), which can be hydrolyzed to 3-amino-2-phenylindan-1-one (7). Attempts to perform a similar cyclization sequence with 3-chloro-2-pyridylindan-1-ones failed.

The sprouting of new blood vessels, or angiogenesis, is necessary for any solid tumor to grow large enough to cause life-threatening disease. Vascular endothelial growth factor (VEGF) is one of the key promoters of tumor induced angiogenesis. VEGF receptors, the tyrosine kinases Flt-1 and KDR, are expressed on vascular endothelial cells and initiate angiogenesis upon activation by VEGF. 1-Anilino-(4-pyridylmethyl)-phthalazines, such as CGP 79787D (or PTK787/ZK222584), reversibly inhibit Flt-1 and KDR with IC50 values 50 = 34 nM). Modification of the 1-anilino moiety afforded derivatives with higher selectivity for the VEGF receptor tyrosine kinases Flt-1 and KDR compared to the related receptor tyrosine kinases PDGF-R and c-Kit. Since these 1-anilino-(4-pyridylmethyl)phthalazines are orally well absorbed, these compounds qualify for further profiling and as candidates for clinical evaluation.
