Into a 250-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of (4-bromo-2-tert-butoxyquinolin-6-yl)(4-chlorophenyl)methanone (4 g, 9.55 mmol, 1.00 equip) in tetrahydrofuran (65 mL). To the resulting mixture was then added (4-chlorophenyl)magnesium bromide (8.2 mL, 1.30 equip, 1 M) dropwise with stirring at 0° C. The resulting solution was stirred for 2 h at 0° C. The reaction was then quenched by the addition of water. The resulting solution was extracted with ethyl acetate (3×150 mL) and the organic layers combined. The resulting mixture was washed with water (2×100 mL) of water and brine (1×100 mL). The resulting mixture was dried over anhydrous sodium sulfate. The residue was applied onto a silica gel column with ethyl acetate:petroleum ether (1:4) to yield (4-bromo-2-tert-butoxyquinolin-6-yl)bis(4-chlorophenyl)methanol as white solid. (ES, m/z): [M+H]+ 532
