Substituted 3-Aminothienopyridine-2-carboxamide as a Synthon for Polyheterocyclic Compounds. Preparation of New Pyridothieno-1,2,3-triazines and Related Derivatives

Pyridothieno-1,2,3-triazines (2) and (3) were synthesized from 3-aminothienopyridine (1) by diazotization and subsequent treatment with electrophilic reagents.Reaction of triazinone (2) with phosphorus oxychloride lead to a mixtur
