Reaction Conditions

Reaction Steps

To a solution of 5-hydroxy-2-nitrobenzaldehyde (500 mg) in N,N-dimethylformamide (4.3 mL) were added sodium chlorodifluoroacetate (456 mg), sodium hydroxide (120 mg) and water (0.060 mL) at room temperature, and the mixture was stirred at 125° C. for one hour. The reaction mixture was cooled to room temperature, diluted with water and then extracted with ethyl acetate. The organic layer was washed successively with water and saturated saline, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluting solvent: ethyl acetate-hexane) to obtain the title compound (240 mg).
