4-Bromo-3-(trifluoromethyl)nitrobenzene (2700 mg, 10 mmol) was dissolved in DMF (15 mL), and allyl alcohol (1750 mg, 30 mmol), tetrabutylammonium chloride (2780 mg, 10 mmol), palladium acetate (120 mg, 5 mol %), and triethylamine (3 mL, 21 mmol) were added thereto. The resulting mixture was stirred under argon atmosphere at 90° C. for 0.5 hours. The reaction solution was partitioned between water and ethyl acetate. The organic layer was washed with saturated brine and concentrated under reduced pressure. The residue was purified by silica-gel column chromatography (n-hexane:ethyl acetate=4:1) to give 3-(4-nitro-2-(trifluoromethyl)phenyl)propionaldehyde (1700 mg, 69%) as a light-yellow oil.
