3-(4-methoxyphenyl)propionic acid amide (10.3 mg, 0.059 mmol) prepared in Reference Synthetic Example 3 was dissolved in tetrahydrofuran (500 μl) in nitrogen atmosphere, tetrakistriphenylphosphine palladium (1.4 mg, 0.0012 mmol) was added under cooling with ice, and a tetrahydrofuran solution of tri-n-butyltin hydride (20 μl, 0.074 mmol) was dropwise added. After stirring for 10 minutes, the solution was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=3:1) to give the desired compound (E)-2-{tri(n-butyl)stannyl}-3-(4-methoxyphenyl)acrylamide (18.6 mg, 68%) as a colorless oily substance.
