In this study, two different methods were described for the synthesis of 2-(aryl)-3-((2-oxo-2-(2-oxo-2H-chromen-3-yl)ethyl)amino)imidazolidin-4-one derivatives under microwave irradiation. The first method was step by step method. In step by step method, 3-(2-hydrazinylacetyl)-2H-chromen-2-one and aromatic aldehydes in 1 mL of absolute ethanol were irradiated with appropriate power within 3-10 min to obtain imine products. Then, the imine […]
