Reaction Steps
To a mixture of 4-(3-aminophenyl)-3-oxo-2-benzyl-3,4-dihydropyrido[2,3-b]pyrazine (150 mg), benzylsulfonyl chloride (96 mg) and pyridine (0.04 ml) in 1,4-dioxane (3 ml) was stirred at 80° C. for 2 hours. The mixture was poured into a mixture of ethyl acetate and water. The organic phase was washed with water and brine, dried over magnesium sulfate, concentrated, and subjected to silica gel column chromatography (hexane-ethyl acetate 1:1) to afford 4-(3-benzylsulfonylaminophenyl)-3-oxo-2-benzyl-3,4-dihydropyrido[2,3-b]pyrazine (49 mg) as a solid.
