Reaction Steps

A mixture of 7-benzyl-4-hydroxy-8-oxo-7,8-dihydro-[2,7]naphthyridine-3-carboxylic acid methyl ester (20 mg, 0.065 mmol) and N-(2-amino-ethyl)-acetamide (20 mg, 0.19 mmol), in EtOH (2 mL) was refluxed for 16 h. After cooling to r.t., AcOH (0.1 mL) and water (20 mL) were added. The resulting cloudy solution was extracted with EtOAc. The organic layer was dried over MgSO4 and concentrated. The crude product was purified by silica gel chromatography (0-10% MeOH/CH2Cl2) to give 13 mg of the title compound as an off-white solid. MS: (+) m/z 381.34 (M+1).
