実験手順

In 3 mL of dimethylformamide, 50 mg (0.19 mmol) of 4-bromo-3-(trifluoromethyl)nitrobenzene was dissolved, and 33 mg (0.56 mmol) of allyl alcohol, 43 mg (0.19 mmol) of tetrabutylammonium bromide, 2.1 mg (5 mol %) of palladium acetate and 52 μL (0.37 mmol) of triethylamine were added thereto and the mixture solution was stirred in an argon atmosphere at 90° C. for two hours. The reaction solution was partitioned between water and ethyl acetate, and the organic layer was washed with a saturated sodium chloride solution and concentrated under reduced pressure. The product was purified by a silica gel column (n-hexane:ethyl acetate=5:1) to obtain 78 mg (79%) of a target product as a pale yellow oil.
