    Abstract: Cytidine-5''-diphosphate choline and deoxycytidine-5''-diphosphate choline are produced by reacting cytidine (or deoxycytidine)-5''monophosphate with a choline phosphoramidate. Choline phosphoramidates of the formula WHEREIN R1 and R2 represent hydrogen, a hydrocarbon residue having at most seven carbon atoms, or R1 and R2 taken together represent a five- or six-membered heterocyclic ring are prepared by reacting phosphorylcholine with an amine.
