Abstract

Abstract 2-[3-Methyl-4 (4-dialkylaminobenzylidene)-5-oxo-4, 5-dihydropyrazol-1-yl] cyclopenta [d] pyrimidin-4 (3 H)-ones were synthesized by consecutive transformation of 2- hydrazinocyclopenta [d] pyrimidin-4 (3 H)-one prepared from benzylideneaminoguanidine and ethyl 2-oxocyclopentanoate.
