Reaction Conditions

Reaction Steps

To a solution of ethyl 3-amino-7-bromo-1,6-naphthyridine-2-carboxylate (47 mg, 0.16 mmol) and DIPEA (83 μL, 0.48 mmol) in DCM (1.5 mL), a solution of benzyl chloroformate (68 μL, 0.48 mmol) was added and the resulting mixture was heated at 60° C. in a sealed vial for 14 h. The crude reaction mixture was then concentrated under reduced pressure and the residue was purified by flash chromatography (24 g silica gel column, eluting with 0-60% EtOAc/hexanes) to afford the sub-title compound (41 mg, 60%). LCMS (ESI) calc. for C19H17BrN3O4[M+H]+: m/z=430.0. found: 429.9.
