Phosphorylation of citrulline (Cit) has been achieved using inorganic cyclo-triphosphate (P3m) in aqueous solution. The optimum condition for the phosphorylation of Cit with P3m is Cit : P3m = 1.75 M : 0.5 M, pH 12 and 10°C. N2-(Phosphono)citrulline was synthesized with the yield of more than 85 %. The reaction mechanism of Cit with P3m was discussed.
