Summary
Nucleoside phosphoramidates derived from polyamines containing at least three amine groups are strongly adsorbed by sodium and magnesium montmorillonite clays even from very dilute solutions. Heating the dried clay-phosphoramidate mixture results in the production of small amounts of the dinucleotides.
