The synthesis of dimethyl benzothiazol-2-yl, 2-thienyl, and 1-methylbenzimidazol-2-yl carbinols and their acylation with acetic anhydride in the presence of perchloric acid have been performed. A method for the synthesis of 4-(benzothiazoI-2-yl)-2,6-dimethylpyrylium and 4-(2-thienyl)-2,6-dimethylpyrylium perchlorates has been developed; these substances are converted by treatment with aqueous ammonia, into the corresponding 4-(2-hetaryl)-2,6-di-methylpyridines.
