Reaction Steps

Into a 100-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 4,8-dibromo-2-(tert-butoxy)-6-[(4-chlorophenyl)carbonyl]quinoline (440 mg, 0.88 mmol, 1.00 equip) in tetrahydrofuran (30 mL). To the resulting mixture was then added (4-chlorophenyl)magnesium bromide (2.67 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 (50 mL). 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-(tert-butoxy)quinolin-6-yl]methanol as a yellow solid.
