Abstract

New 5(6)-phenylsulphonyloxy-benzimidazole-2-carbamates are of formula (I): (where R1 is 1-4C alkyl; R2 and R3 are H, OH, 1-4C alkoxy, halogen, CF3, 1-1C alkyl, 2-5C alkoxycarbonyl or CN). (I) are esp. active against strongyloids in ruminants. A typical cpd. is (I; R1=Me, R2=R3=H). In an example, this is prepd. by reacting 2-methoxycarbonylamino-5(6)hydroxybenzimidazole with benzenesulphonyl chloride.
