To a solution of 4-(4-(4-(4-chlorophenyl)phthalazin-1-ylamino)phenylthio)quinolin-6-ol (0.062 g, 0.12 mmol) in THF at 0° C., was added NaH (0.018 g, 0.73 mmol). The mixture was stirred at 0° C. for 30 minutes. 1-Chloro-2-(methylsulfonyl)ethane (0.035 g, 0.24 mmol) and trace amount of NaI were added. The mixture was stirred and warmed to RT for 15 h. The reaction was quenched with sat. NH4Cl, and extracted with DCM. The combined organic layers were washed with brine, dried, filtered and concentrated. The crude product was purified via column chromatography on silica gel (RediSep 40 g column, gradient elution with 0-50% (90:10:1 DCM/MeOH/NH4OH-DCM) to afford 4-(4-chlorophenyl)-N-(4-(6-(2-(methylsulfonyl)ethoxy)quinolin-4-ylthio)phenyl)phthalazin-1-amine as a light yellow solid. MS: m/z=[M+H]+. 614.0 Calc'd for C32H25ClN4O3S2: 613.1.
