Procedure

To a solution of 2-bromothiazole (0.088 mL, 0.985 mmol) in THF (2.99 mL) cooled to 0° C. was added isopropylmagnesium chloride (0.493 mL, 0.985 mmol). After 50 min, 3-bromo-2-fluorobenzaldehyde (0.200 g, 0.985 mmol) was added. The reaction mixture was allowed to warm to room temperature overnight. After 12 hr, the reaction was quenched with saturated aqueous NH4Cl. The reaction mixture was diluted with CH2Cl2. The layers were separated. The aqueous phase was extracted with CH2Cl2 (2×). The organic phases were combined, dried over Na2SO4, filtered, and concentrated to afford the title compound as a brown liquid.
