Abstract

Methyl 3-aroyl-1-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-2,4-dihydroxy-5-oxo-2,5-dihydro-1H-pyrrole-2-carboxylates reacted with ethylenediamine to give methyl-5-aryl-8-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-6,7-dioxo-2,3,4,6,7,8-hexahydropyrrolo[2,3-e][1,4]diazepine-8a(1H)-carboxylates. The product structure was confirmed by ¹H NMR and IR spectra.
