Synthesis and antimicrobial activity of new pyridothienopyrimidines and pyridothienotriazines

5-Acetyl-3-amino-4-aryl-6-methylthieno[2,3-b]pyridine-2-carboxamides (5a,b) were reacted with triethyl orthoformate or nitrous acid to give the corresponding pyrimidinones 6a,b and triazinones 7a,b. The reaction of 5a,b with acetic anhydride was carried o
