Abstract
A new method has been developed for the synthesis of 4-(benzothiazol-2-yl)-2,6-dimethylpyrylium perchlorate from 2,6-dimethyl-γ-pyrone and 2-lithiobenzothiazole. The reaction of this salt with ammonia and with primary and secondary amines, hydrazine, phenylhydrazine. and hydroxylamine leads to the formation of difficultly accessible hetaryl-substituted benzothiazoles.
