Abstract
1-(4-Fluorobenzyl)-2-chloro-1H-benzo [d]imidazole was synthesized from o-phenylenediamine and ethyl acetoacetate by cyclization,N-alkylation,hydrolyzation and chlorination.The effects of the reaction formula on the yield of the product were studied.The optimized conditions was confirmed.The overall of the product was 56.4%.The structure of the product was confirmed by 1H NMR.
