실험 절차

A mixture of methyl 7-bromo-1-(t-butoxycarbonyl)-2,3-dihydro-1H-1-benzazepine-4-carboxylate (2.0 g), 4-morpholinophenyl borate (1.2 g), and 1M potassium carbonate solution (15 ml), ethanol (15 ml) and toluene (100 ml) was stirred under argon atmosphere at room temperature for 20 minutes. To the mixture was added tetrakis(triphenylphosphine)palladium (0.24 g), and the mixture was refluxed under argon atmosphere for 12 hours and extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried with anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified with silica gel column chromatography (ethyl acetate/hexane) to give methyl 1-(t-butoxycarbonyl)-7-(4-morpholinophenyl)-2,3-dihydro-1H-1-benzazepine-4-carboxylate (3.64 g) as pale yellow crystals.
