A mixture of 7-benzyl-1-cyano-4-hydroxy-8-oxo-7,8-dihydro-[2,7]naphthyridine-3-carboxylic acid methyl ester (26 mg, 0.078 mmol) and methylamine (1 mL, 2M in THF) in 2 mL of EtOH was heated in a sealed tube at 80° C. for 4 h. After the mixture was cooled to r.t., solvent was evaporated in vacuo. The residue was chromatographed (0-10% EtOAc/CH2Cl2+1% AcOH) to give 18 mg of the title compound as a white solid. MS: (+) m/z 335.02 (M+1).
