Procedure

To a solution of 6-(6,7-dimethoxy-4-quinolyloxy)-5-fluoro-2-naphthylamine 2HCl (Step c, 200 mg, 0.46 mmol), thiophene-2-carboxylic acid (120 mg, 0.91 mmol, Aldrich) and DIEA (353 mg, 2.74 mmol, Aldrich) in dry DMF was added PyBOP (476 mg, 0.91 mmol, Fluka) at RT. The reaction was stirred for 16 h. It was diluted with 40 mL of EtOAc and washed with saturated aqueous NaHCO3, followed by brine. The organic phase was dried over Na2SO4 and concentrated in vacuo. The residue was purified by silica gel column chromatography (EtOAc) to give the title compound as a yellow solid. MS (ESI, pos. ion) m/z: 475.0 (M+1). Mass Calc'd for C26H19FN2O4S: 474.10.
