18.0 g (46.4 mmol) of 3-[2-(t-butoxycarbonylamino)ethoxy]-4-iodobenzonitrile was dissolved in 200 ml of dimethylformamide (DMF). 13.3 g (92.8 mmol) of methyl 2-acetamidoacrylate, 2.82 g (9.28 mmol) of tris(2-methylphenyl)phosphine, 1.04 g (4.64 mmol) of palladium (II) acetate and 12.9 ml (92.8 mmol) of triethylamine were added to the obtained solution, and they were stirred at 115° C. for 4 hours. The solvent was evaporated to obtain the crude product, which was purified by the silica gel column chromatography to obtain the title compound.
