Firstly, 1 mmol of the intermediate 2 or 3 was added to 1 mmol of various azole derivatives in the presence of 1 mmol of potassium carbonate and triethylamine in equal proportions and were refluxed at 75 °C for 24 h in acetonitrile as solvent. The progress of the reaction was controlled by TLC. The solvent was evaporated by rotary and extraction was done with ethyl acetate solvent. The organic part was collected and dehydrated with sodium sulfate, after filtration, the solvent was evaporated by rotary. Finally, the purification was conducted by plate chromatography. The final products of (4a-4l) were confirmed using 1HNMR, 13CNMR, MASS, and IR spectroscopic methods.
