To a solution of (4-chloroquinolin-6-yl)(thiazol-4-yl)methanone (52 mg, 0.189 mmol) in THF (2 mL) was slowly added (4-chlorophenyl)magnesium bromide (0.246 mL, 0.246 mmol, 1M in THF) and the resulting solution was kept at 0° C. for 2 hr. The reaction was quenched with saturated NH4Cl at 0° C. and the aqueous mixture was extracted with EtOAc twice. The combined organics were concentrated and purified by silica column (40% EtOAc/hexanes) chromatography to yield (4-chlorophenyl)(4-chloroquinolin-6-yl)(thiazol-4-yl)methanol. (ES, m/z) [M+H]+ 387, 389.
