Reaction Steps

197 mg (0.26 mmol)) of 3-[(2S)-2-(benzenesulfonylamino)-3-[4-(1-benzyloxycarbonyl-4-piperidyloxy)phenyl]propoxy]-4-iodobenzonitrile and 74.4 mg (0.52 mmol) of methyl 2-acetaminoacrylate were dissolved in 6 ml of acetonitrile. 7.3 mg (0.03 mmol) of palladium (II) acetate, 55 mg (0.18 mmol) of tri-o-tolylphosphine and 96 mg (0.52 mmol) of tributylamine were added to the solution, and they were heated under reflux overnight. The solvent was distilled off and the residue was treated with ethyl acetate as the extractant in an ordinary manner to obtain the crude product, which was purified by the silica gel column chromatography to obtain the title compound.
