A mixture of methyl chlorothioimidate, isocyanide and pyrinidine react in a sequence of N-imidoylpyridinium formation then cycloaddition step, to give 1-amonoimidazo [1,5-a] pyridazine, pyrimidine and pyrazine allows the preparation of corresponding fused 1 -amino-3-(methylthio) imidazolium chlorides.
