Reaction Steps

To a solution of 4.37 g of ethyl 7-amino-8-bromo-6-chloro-1,2,4,5-tetrahydro-3H-3-benzazepine-3-carboxylate in 40 ml of DMF were added 2.1 ml of ethyl acrylate, 230 mg of tris-o-tolylphosphine, 85 mg of palladium(II) acetate, and 3.6 ml of triethylamine, followed by stirring at 120° C. for 3 hours. The reaction mixture was diluted with EtOAc, washed with water and saturated brine, dried over anhydrous sodium sulfate, and then filtered, and the filtrate was concentrated under reduced pressure. The resulting yellow solid was stirred and washed in diisopropylether to obtain 3.125 g of ethyl 7-amino-6-chloro-8-[(1E)-3-ethoxy-3-oxoprop-1-en-1-yl]-1,2,4,5-tetrahydro-3H-3-benzazepine-3-carboxylate as a pale yellow solid.
