N,N,N″-Trisubstituted guanidines (most of them N″-aryl-N-azacycloalkanecarboximidamides) are prepared in generally good yields by S-methylation of monosubstituted thioureas with methyl iodide in methanol or acetone and reaction of the resultant methyl carbamimidothioate hydroiodides with secondary amines in boiling tert-butyl alcohol or acetonitrile.
