The method developed for the synthesis of thiazolo[3,2‐ a ]pyridinium salts has been extended to the first synthesis of simple thiazolo[3,2‐ a ]pyrimidinium, thiazolo[3,2‐ a ]‐pyrazinium and thiazolo[2, 3‐ b ]benzo[ d ]thiazolium salts. No method could be found for the cyclization of 4′‐bromo‐2‐(2‐benzoxazolylthio)acetophenone to the thiazolo[2,3‐ b ]‐benzoxazolium system.
