Reaction Steps
The mixture of 2-methyl-4-[3-(3,5-dichlorobenzoylamino)phenyl]-3-oxo-3,4-dihydropyrido[2,3-b]pyrazine (4.4 g), N-bromosuccinimide (2.39 g) and benzoylperoxide in chloroform (40 ml) was refluxed for 3 hours. The mixture was washed with water and extracted by chloroform (80 ml), and evaporated. The crude product was purified by chromatography to obtain 2-bromomethyl-4-[3-(3,5-dichlorobenzoylamino)phenyl]-3-oxo-3,4-dihydropyrido[2,3-b]pyrazine (1.4 g).
