Reaction Steps

A mixture of 2-(3-acetamidophenylamino)-3-aminopyridine (1.0 g) and 3-(3-pyridyl)pyruvic acid (0.82 g) in ethanol (50 ml) was stirred under reflux for 6 hours. After evaporation of the solvent, crude residue was chromatographed on silica gel and crystallized from ethyl acetate to give 4-(3-acetamidophenyl)-2-(3-pyridyl-methyl)-3-oxo-3,4-dihydropyrido[2,3-b]pyrazine (1.04 g).
