N-(2-formamidophenyl)-N',N"-bis-carbonylguanidines bearing an optionally substituted phenoxy, phenylthio, phenylsulfinyl or phenylsulfonyl group in the 4- or 5-position of the 2-(formamido)-phenyl group are anthelminetic agents. The compounds, of which N-(2-formamido-4-phenylthiophenyl)-N',N"-bis-carbomethoxyguanidine is a typical example, are prepared through the reaction of isothiourea-S-alkyl ether and an appropriately substituted 2-aminoformanilide.
