実験手順

A mixture of 0.248 g of 2-(p-bromophenyl)-5-methyl-pyridine, 0.196 g of N-bromosuccinimide, 20 mg of dibenzoyl peroxide and 5 ml of carbon tetrachloride was heated to reflux for 2.5 hours while gassing with nitrogen. The reaction mixture was subsequently left to cool to room temperature and suction filtered. The residue was rinsed with carbon tetrachloride. The filtrate was concentrated in a vacuum, there being obtained 0.360 g of crude 2-(p-bromophenyl)-5-bromomethyl-pyridine as brownish crystals.
