Procedure

To a suspension of 2-anilino-6-[(E)-3-methoxy-3-oxo-1-propenyl]-7-methyl-1-phenyl-1,8-naphthyridin-4(1H)-one (10 mg, 0.025 mmol) in CH3CN (2.0 mL) was added 1N NaOH (2.0 mL). The suspension was stirred at room temperature for 18 h. The mixture was diluted with water (10 mL) and extracted with EtOAc. The organic layer was dried over MgSO4 and concentrated in vacuo to afford (2E)-3-(7-anilino-2-methyl-5-oxo-8-phenyl-5,8-dihydro-1,8-naphthyridin-3-yl)-2-propenoic acid (6.2 mg, 63%): LCMS RT: 2.37 min, MHR: 398.3, Rf=0.51 (EtOAc).
