Reaction Steps

To a solution of 7-(6,7-dimethoxyquinolin-4-yloxy)naphthalen-2-amine (0.168 g, 0.48 mmol) in 20 mL of CH2Cl2 was added K2CO3 (0.134 g, 0.96 mmol), and pyridine (1 mL). The mixture was cooled to 0° C. and m-toluenesulfonyl chloride (0.110 g, 0.58 mmol) was added and the solution was stirred for 16 h at RT under an atmosphere of nitrogen. The reaction was diluted with water and extracted with CH2Cl2 3×. The organic layer was washed with brine, dried (Na2SO4), filtered and concentrated. The residue was purified using a Gilson Prep HPLC system. The fractions were collected, combined, treated with NaHCO3(aq) and extracted with EtOAc 3×. The organic layer was dried (Na2SO4), filtered and concentrated to afford the desired compound. MS (ESI, pos. ion) m/z: 501.0 (M+1). Mass Calc'd for C28H24N2O5S: 500.573.
