To a mixture of 6-(6,7-dimethoxy-4-quinolyloxy)-2-naphthylamine (Step c, 34.6 mg, 0.1 mmol) and K2CO3 in dry CH2Cl2 (10 mL, Aldrich) was added 2-methoxybenzoyl chloride (25.5 mg, 0.15 mmol, Aldrich). The reaction was stirred at RT for 3 h. The volatile portion was removed in vacuo. To the residue was added 15 mL of MeOH and the mixture was stirred at RT for 30 min. The MeOH was removed in vacuo. The resulting residue was diluted in EtOAc (50 mL) and washed with water and brine. The organic phase was dried over MgSO4 and concentrated. The resulting brown residue was purified by silica gel column chromatography (EtOAc) to give the title compound as a white solid. MS (ESI, pos. ion) m/z: 481.4 (M+1). Mass Calc'd for C29H24N2O5: 480.17.
