실험 절차

The solution of 2-bromomethyl-4-[3-(3,5-dichlorobenzoylamino)phenyl]-3-oxo-3,4-dihydropyrido[2,3-b]pyrazine (285 mg) and 2-phenylimidazole (734 mg) in N,N-dimethylformamide (30 ml) was stirred for 3 hours at 80° C. The mixture was poured into aqueous sodium hydrogencarbonate (150 ml) and extracted by ethyl acetate (150 mg). The organic layer was evaporated and chromatographed to obtain 2-[(2-phenylimidazol-1-yl)methyl]-4-[3-(3,5-dichlorobenzoylamino)phenyl]-3-oxo-3,4-dihydropyrido[2,3-b]pyrazine (52 mg) in brown powder form.
