实验过程

A mixture of (1E,4E)-ethyl 8-bromo-2-(tert-butoxycarbonylamino)-3H-benzo[b]azepine-4-carboxylate (2.05 g, 5 mmol), 3-cyanophenylboronic acid (1.47 g, 10 mmol), CsF (2.28 g, 15 mmol), and Pd(PPh3)4 (0.345 g, 0.3 mmol) in anhydrous THF (100 mL) was refluxed for 12 h. After cooling to room temperature, the reaction mixture was poured into water and extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered, and concentrated under reduced pressure to give the crude material that was purified by silica gel flash column chromatography to afford 1.12 g (52%) of (1E,4E)-ethyl 2-(tert-butoxycarbonylamino)-8-(3-cyanophenyl)-3H-benzo[b]azepine-4-carboxylate.
