Synthesis of several derivatives of thieno[2,3‐ e ]‐1,2,4‐triazines has been achieved via the action of phosphorus pentasulfide on 6‐vinyl‐ or 6‐acylmethyl‐5‐oxo‐1,2,4‐triazine derivatives. During these investigations interesting synthetically useful functions for phosphorus pentasulfide in pyridine were observed, among which the deamination of certain N ‐amino heterocycles is unprecedented.
