실험 절차

Methyl 7-bromo-1-isobutyl-2,3-dihydro-1-benzazepine-4-carboxylate (0.90 g) was dissolved in toluene/ethanol/water (=10/1/1, 41 ml). To the solution were added 4-(2-butoxyethoxy)phenyl borate (0.76 g) and potassium carbonate (0.18 g), and the mixture was stirred under argon atmosphere for 30 minutes. To the mixture was added tetrakistriphenylphosphinepalladium (123 mg), and the mixture was heated to reflux for 14 hours. After cooled to room temperature, the reaction solution was added to water, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine and dried with magnesium sulfate. The solvent was removed under reduced pressure, and the resulting residue was purified with silica gel column chromatography (hexane/ethyl acetate=8/1) to give methyl 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-2,3-dihydro-1-benzazepine-4-carboxylate (0.75 g).
