    摘要: The present invention describes a new process for the preparation of (poly)aminoalkylaminoacetamide compounds of epipodophyllotoxin useful for their applications in therapeutics as anticancer agents. This process comprises a step of condensation of a primary-amine-containing reactant, whose amine functions are not protected, with β-chloroacetamido-4′-epipodophyllotoxin in a polar aprotic organic solvent.
