To a dioxane solution (10 mL) of triphenylphosphine (139 mg, 0.53 μmol), palladium acetate (40.0 mg, 0.18 μmol) and triethylamine (0.59 μL, 4.23 mmol) were added in this order. The mixture was stirred for 5 minutes at 75° C. A dioxane solution (15 mL) of the compound (1) (1.03 g, 3.52 mmol) and acrylonitrile (0.46 μL, 7.04 mmol) were added thereto, and the reaction solution was heated to reflux for 11.5 hours. Generation of a product was confirmed by TLC (HexH:AcOEt=4:1), and then palladium powder was removed by cotton filtration. The residue was purified by column chromatography (HexH:AcOEt=4:1), and compound (2) (0.14 g, 18%, trans:cis=97:3) was obtained as a white powder. Thus, compound (1) (0.37 g, recovery rate 37%) was recovered as a white powder.
