Reaction Steps

A mixture of ethyl 3-{[(benzyloxy)carbonyl]amino}-7-bromo-1,6-naphthyridine-2-carboxylate (22 mg, 0.051 mmol), 4,4,5,5-tetramethyl-2-vinyl-1,3,2-dioxaborolane (43 μL, 0.26 mmol), tetrakis(triphenylphosphine)palladium(0) (4 mg, 0.004 mmol), and potassium carbonate (21 mg, 0.15 mmol) in 1,4-dioxane (500 μL) and water (50 μL) in a vial was deoxygenated and purged with nitrogen several times. The vial was sealed under nitrogen and then heated at 95° C. for 3 h. The crude reaction mixture was filtered through a pad of diatomaceous earth and the inorganics were washed thoroughly with EtOAc. The filtrate was concentrated under reduced pressure and the residue was purified by flash chromatography (24 g silica gel column, eluting with 0-50% EtOAc/hexanes) to afford the sub-title compound (10 mg, 50%). LCMS (ESI) calc. for C21H20N3O4 [M+H]+: m/z=378.1. found: 378.1.
