실험 절차

To a stirring solution of 1-chloro-2-iodobenzene (7.05 g, 29.6 mmol) in tetrahydrofuran (Volume: 15 mL) at −15° C. was added isopropylmagnesium chloride (17.24 mL, 34.5 mmol). The mixture was allowed to stir for 30 minutes, at which time 3-bromo-2-fluorobenzaldehyde (5 g, 24.63 mmol) was added. The reaction mixture was stirred overnight. The reaction was quenched with saturated aqueous NH4Cl. The reaction mixture was extracted with EtOAc (3×). The organics were combined, rinsed with brine, dried over Na2SO4, filtered, and concentrated to afford the title compound (7.5 g, 96%).
