Reaction Steps

4 g (5.7 mmol) of bis(triphenylphosphine)palladium(II) chloride are added to a degassed solution of 37.13 g (132 mmol) of 4-cyano-2-methoxyphenyl trifluoromethanesulfonate, 35 ml (245 mmol) of tert-butyl acrylate and 90 ml (645 mmol) of triethylamine in DMF (250 ml). The solution is stirred at 100° C. under a protective gas atmosphere for 24 h. Ice-water (1000 ml) is then added, and the suspension is extracted with ethyl acetate (3×100 ml). The organic phase is washed with saturated sodium chloride solution, dried over magnesium sulfate and concentrated. The residue is purified by column chromatography (silica gel, mobile phase: cyclohexane/ethyl acetate 10:1). 24.6 g (72% of theory) of the title compound are obtained as a white solid.
