3,5-Dichlorobenzoyl chloride → 4-[3-(3,5-Dichlorobenzoylamino)phenyl]-2-(3-pyridylmethyl)-3-oxo-3,4-dihydropyrido[2,3-b]pyrazinehydrochloride

Participants

Reaction Steps

To a solution of 4-(3-aminophenyl)-2-(3-pyridylmethyl)-3-oxo-3,4-dihydropyrido[2,3-b]pyrazine (329 mg) in chloroform (5 ml) was added 3,5-dichlorobenzoylchloride (220 mg). The mixture was stirred at room temperature for 15 minutes and concentrated. The residue was crystallized from methanol to give 4-[3-(3,5-dichlorobenzoylamino)phenyl]-2-(3-pyridylmethyl)-3-oxo-3,4-dihydropyrido[2,3-b]pyrazinehydrochloride (370 mg).
