Versuchsvorschrift

A mixture of methyl 7-bromo-1-methoxycarbonyl-2,3-dihydro-1H-1-benzazepine-4-carboxylate (0.3 g), 4-morpholinophenyl borate (0.22 g), 1M potassium carbonate solution (2.5 ml), ethanol (2.5 ml) and toluene (25 ml) was stirred under argon atmosphere at room temperature for 30 minutes. To the mixture was added tetrakis(triphenylphosphine)palladium (0.04 g), and the mixture was refluxed overnight under argon atmosphere and extracted with ethyl acetate. The organic layer was washed with water and saturated brine and dried with anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified with silica gel column chromatography (ethyl acetate/hexane) to give methyl 1-methoxycarbonyl-7-(4-morpholinophenyl)-2,3-dihydro-1H-1-benzazepine-4-carboxylate (0.31 g) as pale yellow crystals.
