Preparation of some fused pyridopyrimidine and pyridothienotriazine derivatives for biological evaluation

Compounds 2 and 9 were formed using 3-(4-chloro-phenyl)-1-pyridin-2-yl propenone (1) and malononitrile or ethyl cyanoacetate, respectively. The pyridine derivative 2 was in turn used as a precursor for the preparation of some pyridopyrimidine and fused py
