Reaction Steps

320 ml (0.32 mmol) of a 1 molar solution of lithium hexamethyl disilazide (LiHMDS) in hexane are placed in 800 ml diethyl ether and combined at ambient temperature with 25.0 g (0.161) 2-chloro-3-fluoro-benzonitrile. The mixture is stirred for 2 h at ambient temperature and after cooling to 0° C. it is combined with 280 ml 3 normal hydrochloric acid. The precipitate formed is suction filtered, washed with water and dried.
