4-Cyano-3-methylisoquinoline → 3-(Bromomethyl)-4-isoquinolinecarbonitrile

Participants

Reaction Steps

39 mg azo-isobutyronitrile are added to a boiling mixture of 400 mg 3-methyl-4-cyano-isoquinoline and 440 mg N-bromosuccinimide in 30 ml carbon tetrachloride. The reaction mixture is refluxed for two hours. After cooling to ambient temperature the precipitate formed is suction filtered and washed with carbon tetrachloride. The filtrate is evaporated down and chromatographed through a silica gel column with methylene chloride as eluant.
