Reaction Steps

Into a 50-mL round-bottom flask, was placed 6-[bis(4-chlorophenyl)methyl]-4-[(piperidin-4-yl)amino]quinolin-2-ol (150 mg, 0.31 mmol, 1.00 equip), dichloromethane (20 mL), triethylamine (0.5 mL), and methyl 5-(chlorosulfonyl)thiophene-2-carboxylate (76 mg, 0.32 mmol, 1.00 equip). The resulting solution was stirred for 1 h at 25° C. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with dichloromethane/methanol (20:1) to yield methyl 5-[4-([6-[bis(4-chlorophenyl)methyl]-2-hydroxyquinolin-4-yl]amino)piperidine-1-sulfonyl]thiophene-2-carboxylate as a yellow solid. LCMS (ES, m/z) 682 [M+H]+
