Abstract A new method for the synthesis of 3-(1,3,4-oxadiazol-2-yl)coumarins is proposed. It is based on the recyclization of 2-(N-aroylhydrazono)coumarin-3-carboxamides, which are readily obtained by the reaction of 2-iminocoumarin-3-carboxamides with arenecarboxylic hydrazides in an acidic medium. Advantages of the given method over alternative synthetic schemes were shown. Proposals on the mechanism of reaction were made.
