An efficient method for the solid-phasesynthesis of substituted guanidines is presented. A variety of alcohols react with resin-bound N,N′-bis(t-butoxycarbonyl)thiopseudourea under Mitsunobu conditions to give the corresponding alkylated thiopseudoureas. The guanidines are liberated from the resin upon exposure to ammonia or primary amines.
