40690-89-9 - Production method
Using N-cyanoethyl-N-hydroxyethyl aniline and p-nitroaniline as raw materials, N-cyanoethyl-N-hydroxyethyl aniline and benzoyl chloride are first benzoylated to obtain an intermediate (I). Then the p-nitroaniline is diazotized and coupled with (I) to obtain the product. The finished product is filtered, ground and dried.
