ABSTRACT An efficient synthesis for the preparation of some 2-amino-5-substituted phenyl- 1, 3, 4-oxadiazoles by using both conventional and microwave method have been devised. The obtained results revealed that, microwave assisted technique is efficient, eco-friendly and inexpensive method which not only give higher yield but also reduces the reaction time significantly. The resulting compounds were characterized by IR, 1H-NMR, UV-Vis and ...
