Abstract
(Z)-3-(4-chlorophenyl)-3-[N,N-di-(4-chloro-3-ethyl-1-methy-5-pyrazole formyl)-amino]-2-ethyl cyanoacrylates was prepared from 4-chlorobenzoyl chloride and ethyl 2-cyanoacetate,by chlorination and ammoniation.afterw-ards the reaction with 4-chloro-3-ethyl-1-methyl-1H-pyrazole-5-carbonyl chloride.The structures were confirmed by 1H NMR,IR and X-ray crystallography,It was proved to be the target compounds.
