This article describes an attractive and one-pot synthesis of the title compound by phosphorylation of just prepared N-substituted guanidines from cyanamide and the desired amine. The method allows a variety of N-substituents to hang on the final phosphoryl guanidine as a function of the wider availability of commercial simple amines.

Regioselective attack of the trivalent phosphorus atom of dialkyl and trialkyl phosphites on either nitrogen or sulfur atom of sulfenamides has been found. The reaction of phenylsulfenamides with dialkyl phosphites yielded phosphorothiolates, whereas the treatment of (2-benzothiazolyl)sulfenamides with dialkyl and trialkyl phosphites gave phosphoramidates in excellent yields.
