Reaction Steps
A mixture of 4-(3-aminophenyl)-2-benzyl-3-oxo-3,4-dihydropyrido[2,3-b]pyrazine (150 mg) and 1-naphthyl isocyanate (94 mg) in dry dioxane (3 ml) was stirred at room temperature for 3 hours. The precipitates were collected and washed with isopropyl ether to give 4-[3-[3-(1-naphthyl)ureido]phenyl]-2-benzyl-3-oxo-3,4-dihydropyrido[2,3-b]pyrazine.
