Procedure

Into a 100-mL round-bottom flask, was placed a solution of 4,8-dibromo-6-[(4-chlorophenyl)carbonyl]-2-methoxyquinoline (1.5 g, 3.29 mmol, 1.00 equip) in tetrahydrofuran (30 mL). To the resulting mixture was then added (4-chlorophenyl)magnesium bromide (9.87 mL, 3.00 equip, 1 M) dropwise with stirring at 0° C. The resulting solution was stirred for 3 h at room temperature. The reaction was then quenched by the addition of saturated sodium bicarbonate (100 mL). The solids were filtered out and washed with ethyl acetate (100 mL), and the ethyl acetate was combined with the filtrate. The resulting solution was extracted with ethyl acetate (100 mL) and the organic layers combined and dried over anhydrous sodium sulfate. The solids were filtered out. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:9) to yield bis(4-chlorophenyl)(4,8-dibromo-2-methoxyquinolin-6-yl)methanol as a yellow solid. LCMS (ES, m/z) 568 [M+H]+
