In this work, a new series of N'-{[4-amino-5-oxo-3-(thiophen-2-yl)-4,5-dihydro-1H-1,2,4-triazol-1-yl]acetyl}-2-oxo-2H-1-benzopyran-3-carbohydrazides (thiophene-triazole-coumarin hybrid molecules) was synthesised from the reaction of 2-[4-amino-5-oxo-3-(thiophen-2-yl)-4,5-dihydro-1H-1,2,4-triazol-1-yl]acetohydrazide and 3-(1H-benzotriazol-1-ylcarbonyl)-2H-chromen-2-ones by using microwave irradiation and conventional heating procedures and their results were compared. the reaction was performed using a very small amount of organic solvent and without using a catalyst.
