Procedure
A mixture of NAPHTHYRIDINONE 2 (1.0 eq), acid from step 3 (1.5 eq), Na2CO3 (3.5 eq; 2M in H2O), Pd(OAc)2 (0.05 eq.) and PPh3 (0.15 eq.) or PdCl2dppf (0.05 eq) in n-propanol-DMF (1:1, 0.1M) was stilled at 70° C. for 2 h. The mixture was cooled to it, quenched with AcOH and diluted with EtOAc. The combined organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated. Flash chromatography (CH2Cl2:EtOAc, 60:40, 2% AcOH) afforded the title compound as a white solid.
