Participants

Reaction Conditions

Reaction Steps

A mixture of 2,3-difluoro-6-hydroxybenzaldehyde (0.93 g), (bromomethyl)benzene (1.11 g) and potassium carbonate (1.22 g) in N,N-dimethylformamide (15 mL) was heated at 70° C. overnight. After cooling to room temperature, the reaction mixture was partitioned between water and ethyl acetate. The organic layer was separated, and the aqueous layer was extracted with additional ethyl acetate three times. The combined organic layers were washed with brine, dried over MgSO4, filtered, and concentrated. The residue was purified by flash chromatography on silica gel to give the title compound.
