Procedure

To a solution of 2-(bromomethyl)-4-(3-succinimidophenyl)-3-oxo-3,4-dihydropyrido[2,3-b]pyrazine (420 mg) in acetonitrile (4 ml) was added 1-acetylimidazole (179 mg). The solution was refluxed for an hour. The mixture was evaporated. The residue was dissolved in water, and to the solution was added sodium carbonate. The mixture was extracted by ethyl acetate. The organic layer was evaporated. The residue was purified by column chromatography to obtain 2-(1-imidazolylmethyl)-4-(3-succinimidophenyl)-3-oxo-3,4-dihydropyrido[2,3-b]pyrazine (105 mg) as yellow powder.
