실험 절차

A mixture of 6-benzyl-1-cyano-4-hydroxy-5-oxo-5,6-dihydro-[2,6]naphthyridine-3-carboxylic acid methyl ester (27 mg, 0.081 mmol), glycine (805 mg, 10.7 mmol), and NaOMe solution (16 mL, 8.06 mmol, 0.5 M in MeOH) was refluxed for 16 h. After the mixture was cooled to r.t., solvent was evaporated in vacuo. The residue was partitioned between EtOAc and water. 1 M HCl was added with vigorous stirring until pH was about 1. The aqueous layer was extracted with additional EtOAc, and the combined organic layer was dried over MgSO4 and concentrated. The crude residue was dissolved in saturated NaHCO3 and washed with ether. The aqueous layer was acidified to pH about 1 with 4 M HCl and extracted with EtOAc. The organic layer was dried over MgSO4 and concentrated to give 33 mg of the title compound. MS: (+) m/z 379.00 (M+1).
