실험 절차

To a stirred suspension of 2-anilino-6-[(E)-3-hydroxy-3-oxo-1-propenyl]-7-methyl-1-phenyl-1,8-naphthyridin-4(1H)-one (40.0 mg, 0.100 mmol) in MeOH (2.0 mL), was added Pd/C (5.3 mg, 10% weight on carbon) under an argon atmosphere, followed by the addition of ammonia formate (19.0 mg, 0.30 mmol) in a single portion. The reaction mixture was heated at reflux for 2 h, cooled and filtered. The filtrate was diluted with water (10 mL) and extracted with EtOAc. The organic layer was dried over MgSO4 and concentrated in vacuo. The residue was washed with water and dried in vacuo to afford 3-(7-anilino-2-methyl-5-oxo-8-phenyl-5,8-dihydro-1,8-naphthyridin-3-yl)propanoicacid (34.5 mg, 86%): LCMS RT: 2.31 min, MH+: 400.4, Rf=0.61 (4:1 EtOAc:MeOH).
