Abstract
One new synthesis technology of N-[2(3,4-dimethoxyphenyl)ethyl]-N'-(2-phenylethyl)-1,6-hexanediamide was designed through chlorination,condensation,hydrolysis,chlorination and condensation reaction with hexanedioic acid monomethyl ester as raw material.The technology has the advantages of simple operation,easy separation and easy purification,while the yield of the compound is up to 75.2%,and it is applicable to large-scale industrial production.The structure of the final product is characteried by 1H NMR.
