Abstract

Derivatives (5-7) of a new heterocyclic system containing the pyrimido[2, 1-a]phthalazine skeleton were obtained by condensation of phthalic anhydride with the appropriate hydrazides (2-4). Moreover the preparation of 9-substituted 1 H-pyrazolo[3′, 4′: 4,5]pyrimido(2,1-a][1,2,4]triazolo[4,3-c]phthalazin-12-ones (20) and (21) is described
