Reaction Steps

A mixture of 7-(2,4-dimethoxy-benzyl)-4-hydroxy-8-oxo-7,8-dihydro-[2,7]naphthyridine-3-carboxylic acid methyl ester (15 mg, 0.041 mmol) and 4-fluorobenzylamine (0.020 mL, 0.14 mmol) in EtOH (2 mL) was refluxed for 16 h. After cooling the mixture to r.t., AcOH (0.1 mL) and water (2 mL) were added. The resulting precipitate was isolated by filtration, washed with cold MeOH/H2O (5 mL, 1:1), and purified by silica gel chromatography (0-2% MeOH/CH2Cl2) to give 15 mg of the title compound. MS: (+) m/z 464.35 (M+1).
