1-(3,4-bis-(3-lower alkoxycarbonyl)-2-thioureido)-phenyl)-1-phenylethylenes, which have anthelmintic activity, are prepared by reacting various 1-(3,4-diaminophenyl)-1-phenylethylenes with an alkoxycarbonylisothiocyanate which is prepared, in turn, from an alkali metal thiocyanate and a lower alkyl haloformate.
