Procedure
To a solution of 1-(4-(6,7-dimethoxyquinolin-4-yloxy) phenyl)-5-oxopyrrolidine-3-carboxylic acid (Step 3, 120 mg, 0.29 mmol), aniline (55 mg, 0.59 mmol), HOBt (58 mg, 0.43 mmol) in 6 mL of DMF was added EDC (82 mg, 0.43 mmol) at RT. The reaction was stirred at RT for 16 h. The mixture was diluted with 50 mL of EtOAc, and the resulting solution was washed with 20 mL of satd. NaHCO3 followed by 20 mL of brine. The organic phase was dried over Na2SO4 and concentrated in vacuo. The crude was purified by silica gel column chromatography (30% to 100% EtOAc/hexane then to 5% MeOH/EtOAc) to afford the title compound as a white solid. MS (ESI pos. ion) m/z: 484.5 (M+H). Calc'd Exact Mass for C28H25N3O5: 483.52.
