Synthesis of new derivatives of 9-(2-pyridyl)-3-aryl(arylalkyl)- -2,4,5(9H)trioxo-7,8-dihydroimidazo[1,2-a][1,3,5]triazepine

A series of new derivatives of 9-(2-pyridyl)-3-aryl(arylalkyl)-2,4,5(9H)trioxo-7,8- dihydroimidazo [1,2-a][1,3,5] triazepine was obtained by condensation of 1-[1-(2-pyridyl) imidazolidine-2-ylidene]-3-aryl(arylalkyl)ureas) with diethyl oxalic acid ester. Considering the structure of the obtained compounds, it can be expected that these compounds can reveal pharmacological activity.
