A mixture of 7-(2,4-dimethoxy-benzyl)-4-hydroxy-8-oxo-7,8-dihydro-[2,7]naphthyridine-3-carboxylic acid methyl ester (20 mg, 0.054 mmol) and methylamine (0.8 mL, 2M in THF) in EtOH (2 mL) was heated in a sealed tube at 80° C. for 16 h. After cooling the mixture to r.t., water (2 mL) was added. The resulting precipitate was isolated by filtration, washed with cold MeOH/H2O (5 mL, 1:1), and dried under vacuum to give 9 mg of the title compound. MS: (+) m/z 370.28 (M+1).
