manufacture example 1
[0251] Add 75 g of N-bromosuccinimide and 0.81 g of azobisisobutyronitrile to a solution of 27.11 g of 3-chloro-o-xylene in 300 ml of carbon tetrachloride, and heat to reflux for 2 hours. The reaction mixture was washed with water and saturated aqueous sodium bicarbonate, the organic layer was dried over anhydrous magnesium sulfate and filtered, and the filtrate was concentrated under reduced pressure to obtain 63.297 g of 1,2-bis(bromomethyl)-3- chlorobenzene.
manufacture example 2
[0253] To 9.5 g of sodium cyanide in 120 ml of aqueous solution was added 57.533 g of 1,2-bis(bromomethyl)-3-chlorobenzene in 120 ml of EtOH and heated to reflux for 30 minutes. The reaction mixture was poured into ice and stirred, and the precipitated solid was filtered off to obtain 32.941 g of 2,2'-(3-chloro-1,2-phenylene)diacetonitrile as a tan solid.
