Reaction Steps

The mixture of 2-methyl-4-(3-biphenylyl)-3-oxo-3,4-dihydropyrido[ 2,3-b]pyrazine (17 g), N-bromosuccinimide (10.6 g) and 2,2′-azobis(4-methoxy-2,4-dimethylvaleronitrile (167 mg) in benzene (200 ml) was refluxed for 2 hours. The mixture was washed with water and evaporated. The crude products was purified by column chromatography to obtain 2-bromomethyl-4-(3-biphenylyl)-3-oxo-3,4-dihydropyrido[2,3-b]pyrazine (5 g).
