N-[2-(Substituted amido)phenyl]-N'-carbonyl-S-substituted isothioureas bearing an optionally substituted phenoxy, phenylthio, phenylsulfinyl or phenylsulfonyl group in the 4- or 5-position of the 2-(substituted amido)-phenyl group are anthelmintic agents. The compounds, of which N-(2-acetamido-4-phenoxyphenyl)-N'-carbomethoxy-S-methylthiourea is a typical example, are prepared through the reaction of S-substituted N-(mercaptohalomethylene)carbamic acid ester and an apropriately substituted 2-aminoanilide, or through alkylation of the corresponding S-unsubstituted thiourea.
具有4-或5-位置的2-(取代酰胺基)苯基团中的可选择取代的苯氧基、苯硫基、苯亚硫氧基或苯砜基的N-[2-(取代酰胺)苯基]-N'-羰基-S-取代异硫脲是驱虫剂。这些化合物,其中N-(2-乙酰氨基-4-苯氧基苯基)-N'-羰基-S-甲基硫脲是一个典型例子,通过S-取代N-(巯基卤代亚甲基)碳酸酯和适当取代的2-氨基苯胺的反应制备,或通过烷基化相应的S-未取代硫脲制备。
