A mixture of (1R)-1-methyl-2-morpholin-4-yl-2-oxoethyl 4-methylbenzenesulfonate (310 mg, 0.858 mmol), 1-allyl-N-(3-ethylphenyl)-1H-pyrrole-2-carboxamide (210 mg, 0.826 mmol), palladium acetate (10 mg, 0.045 mmol), sodium hydrogencarbonate (140 mg, 1.66 mmol) and benzyltriethylammonium chloride (190 mg, 0.834 mmol) in dimethylformamide (5 ml) was stirred for 3 hours at 50° C. Thereto was added an aqueous 5% potassium hydrogensulfate solution and the mixture was extracted with ethyl acetate/toluene(2/1). The organic layer was washed with water, an aqueous sodium thiosulfate solution and an aqueous saturated sodium chloride solution, and dried over magnesium sulfate. The solvent was removed and the residue was purified with silica gel chromatography (hexane:ethyl acetate=5:1→3:1) to give N-(3-ethylphenyl)-1-[(2E)-3-(3-{[(1S)-1-methyl-2-morpholin-4-yl-2-oxoethyl]oxy}phenyl)prop-2-enyl]-1H-pyrrole-2-carboxamide (349 mg, 83%).
