Alternative Names: 2-chloro-3-(4-nitrophenyl)propanenitrile; BRN 1963899; 2-Chloro-3-(4-nitro-phenyl)-propionitrile; Alpha-Chloro-p-nitrohydrocinnamonitrile; 17849-31-9; Hydrocinnamonitrile, alpha-chloro-p-nitro-;

Preparation of 2-chloro-3-(4-nitrophenyl)propanenitrile

Preparation of 2-chloro-3-(4-nitrophenyl)propanenitrile

4.2 kg of p-nitroaniline are dissolved in a hot mixture of 9 l of concentrated hydrochloric acid and 9 l of water, cooled to 30° C, and treated with 24 kg of ice. 7.3 l of 30% sodium nitrite solution are added in within a few minutes with vigorous cooling. The diazonium salt solution is filtered and treated with a solution of 1.76 kg of acrylonitrile in 15 l of acetone. 600 g of copper(II) chloride are then added and a short time thereafter at ca. 18° C evolution of nitrogen begins. The temperature is kept below 30° C by ice-cooling. 2-chloro-3-(4-nitrophenyl)propanenitrile separates and after recrystallization from methanol has m.p. 110° C. The yield of 2-chloro-3-(4-nitrophenyl)propanenitrile  is 5.3 kg.
