A chemospecific one-pot synthesis of easily isolable 2-acetoxyindole-3-carbonitriles was described. The intermediate 2-oxindole-3-carbonitriles successfully prepared from 2-cyano diazoacetanilides without isolation were treated with acetyl chloride and triethylamine to give 2-acetoxyindole-3-carbonitriles. The developed one-pot approach showed broad substrate scope.

The present invention concerns compounds which can inhibit platelet derived growth factor receptor (PDGF-R) activity, preferably such compounds also inhibit the activity of other members of the PDGF-R super family and are selective for members of the PDGF-R super family. The PDGF-R super family includes PDGF-R and PDGF-R related kinases Flt, and KDR. The featured compounds are active on cell cultures to reduce the activity of the PDGF-R and preferably one or more PDGF-R related kinases. An example of a featured compound, A10 (see Figure 1A), and its ability to inhibit growth of tumor cells in vivo is described below. Using the present application as guide, other compounds able to inhibit PDGF-R and preferably Flt and/or KDR can be obtained. Such compounds are preferably used to treat patients suffering from cell proliferative disorders characterized by inappropriate PDGF-R activity.
