実験手順

A mixture of 7-benzyl-1-cyano-4-hydroxy-8-oxo-7,8-dihydro-[2,7]naphthyridine-3-carboxylic acid methyl ester (25 mg, 0.075 mmol), (2-amino-ethoxy)-acetic acid (60 mg, 0.50 mmol), and NaOMe (20 mg, 0.37 mmol) in EtOH (5 mL) was refluxed for 16 h, then heated at 150° C. in a microwave reactor for 2 h. Solvent was evaporated in vacuo, and the residue was partitioned between EtOAc and water. 1 M HCl was added with vigorous stilling until pH about 2, and the organic layer was dried over MgSO4 and concentrated. The crude product was purified by chromatography (5-80% EtOAc/hexanes+2% AcOH) to give 4 mg of the title compound as a pale yellow solid. MS: (+) m/z 423.19 (M+1).
