A new facile solid-phasesynthesis of N,N′,N″-substituted guanidines from an immobilised amine component is described. The resin-bound amine was reacted with di-(2-pyridyl)thionocarbonate to generate the isothiocyanate which was treated with aryl/alkyl amines to yield the corresponding resin-bound thiourea. Desulfurisation of the thiourea was readily achieved by treatment with triphenylphosphine dichloride
