Article abstract of DOI:10.1007/BF00531549

Treatment of 1-R-2 chloroperimidines with potassium or sodium cyanides in DMSO solution leads to facile substitution of the chlorine atom by the CN group and formation of previously unknown 1-R-2-cyanoperimidines.The latter upon heating in polyphosphoric acid are converted to 1-R-2-carbamoylperimidines in good yield.
