A synthetic procedure for the preparation of phosphoramidate prodrugs of C‐nucleosides is reported. Different phosphorochloridates were reacted with 3′‐O‐protected N‐acetyl‐2′‐deoxypseudoisocytidine or 3′‐O‐protected 2′‐deoxypseudoisocytidine, followed by acidic hydrolysis of the protecting group. In the presence of the N‐acetyl moiety, the enolisable keto group of the nucleobase was able to react
