The known azaiminium intermediate, 1‐chloro‐1,3‐bis(dimethylamino)‐3‐phenyl‐2‐azaprop‐2‐en‐1‐ylium perchlorate 1 [1], reacts with 2‐aminothiazole to yield the fully conjugated condensed 1,3,5‐triazinium salt 7 . Various suitably substituted heterocyclic compounds react similarly to afford the corresponding condensed 1,3,5‐triazinium salts. The diazaiminium intermediates 2–5 obtained from several secondary amides give identical products when treated with the same starting compounds. The procedure appears to be of wide application.
