ChemInform Abstract: Piperazine Derivatives of Benzimidazole as Potential Anthelmintics. Part 1. Synthesis and Activity of Methyl‐5‐(4‐Substituted‐piperazin‐1‐yl)benzimidazole‐2‐carbamates.

Abstract The piperazinylnitroanilines (III), prepared by coupling the piperazines (I) with the chloronitroaniline (II), are reduced and subsequently treated with the S‐methylisothiourea (IV) to produce the piperazinylbenzimidazoles (V).
