2,5-dipyridyl-1,3,4-oxadiazoles were synthesized from nicotinic acid/ isonicotinic acid through acylation, hydra-zine decomposition and ring-closing reaction, and each step yields were above 80% . This method has such advantages as mild reac-tion conditions, simplified operational procedure and easiness in getting the raw materials. What’s more, it can be carried out under mild conditions applicable for the productions in the laboratory.
