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) and 1-aminomethyl-cyclobutanecarboxylic acid tert-butyl ester (55 mg, 0.30 mmol) in EtOH (2 mL) was heated at 140° C. in a microwave reactor for 2 h. Solvent was evaporated in vacuo, and the residue was purified by chromatography (0-30% EtOAc/hexanes+2% AcOH) to give 32 mg of the title compound as a viscous oil. MS: (+) m/z 489.33 (M+1).
