The Gould-Jacobtype of reaction for the synthesis of ethyl 4-oxo-8,10-substituted-4,8-dihydropyrimido[1,2-c]pyrrolo[3,2-e]pyrimidine-3-carboxylates 5 has been carried out conventionally by the condensation between 4-aminopyrrolo[2,3-d]pyrimidines 2 and diethyl ethoxymethylenemalonate 3 via acyclic intermediates diethyl N-[5,7-substituted-7H-pyrrolo[2,3-d]pyrimidin-4-yl]aminomethylenemalonates 4 and
