Methyl p-chlorocinnamate is an organic chemical, often used in industry, pharmaceutical industry, etc., obtained by reacting chlorobenzaldehyde with acetic anhydride. The chlorobenzene formaldehyde, acetic anhydride and sodium acetate with reaction 13 h under 180 ℃. After the reaction, it is slightly cold. Pour into the water, filter and wash the filter cake with water. Dissolve the cake repeatedly with ammonia until only a small amount of brownish-yellow sticky remains remain. The ammonium salt solution was filtered, then the chlorocinnamic acid was precipitated out with 3N dilute sulfuric acid, and the product was filtered and dried.

Methyl p-chlorocinnamate is mainly used to synthesize methyl bromomethyl cinnamate from the upstream raw material of the antithrombotic agent ozagrel sodium. The methyl methylanilate was prepared by N- butyl diimide bromide bromide and the total yield was 67%.
