Reaction Steps

A flask was charged with 4-(4-chlorophenyl)-N-(4-(6-methoxyquinolin-4-ylthio)phenyl)phthalazin-1-amine (0.325 g, 0.624 mmol), AcOH (5.71 ml, 99.8 mmol) and HBr (5.42 ml, 99.8 mmol). The mixture was stirred at 85° C. for 2 h, then cooled to RT and quenched with saturated aqueous NaHCO3 to precipitate a solid. The solid was filtered, washed with water and dried to give 4-(4-(4-(4-chlorophenyl)phthalazin-1-ylamino)phenylthio)quinolin-6-ol as a light yellow solid. MS: m/z=[M+H]+. 508.0 Calc'd for C29H19ClN4OS: 507.0.
