Reaction Steps

To the mixture of 4-bromobenzonitrile (2.6 g, 14.28 mmol), Pd(OAc)2 (0.064 g, 0.286 mmol) and tri-o-tolylphosphine (0.261 g, 0.857 mmol) in dry DMF (20 mL) was added ethyl 2-propenoate (2.282 mL, 21.43 mmol) and TEA (3.98 mL, 28.6 mmol). It was heated at 110° C. for 1 h. Purification via a flash column chromatography then provided the title compound as a white solid (2.7 g, 92% yield). LCMS: rt=3.03 Min, [M+H+]=202.0
