실험 절차

A mixture of 1-benzyl-5-hydroxy-8-methyl-2-oxo-3-phenyl-1,2-dihydro-[1,7]naphthyridine-6-carboxylic acid methyl ester (35 mg, 0.088 mmol), N-(2-amino-ethyl)-N-methyl-methanesulfonamide HCl salt (83 mg, 0.44 mmol), and NaOMe (24 mg, 0.44 mmol) in EtOH (3 mL) was heated at 140° C. for 6 h in a microwave reactor. Solvent was evaporated in vacuo, and the residue was partitioned between EtOAc and 0.1 M HCl. The organic layer was dried over MgSO4 and concentrated. The residue was purified twice by silica gel chromatography (first eluted with 0-2.5% MeOH/CH2Cl2, then with 15-100% EtOAc/hexanes+2% AcOH) to give 16 mg of the title compound as an off-white solid. MS: (+) m/z 521.28 (M+1).
