Versuchsvorschrift

In a mixture of water:ethanol:toluene (1:1:10, v/v, 18.0 ml) were dissolved 4-(2-ethoxyethoxy)phenyl borate (339 mg) and 7-bromo-1-ethyl-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (537 mg). To the solution was added potassium carbonate (357 mg), and the mixture was stirred under argon atmosphere at room temperature for 30 minutes. To the mixture was added tetrakistriphenylphosphinepalladium (50 mg), and the mixture was heated to reflux under argon atmosphere for 14 hours. The mixture was diluted with ethyl acetate, and washed with water and saturated brine, and the organic layer was dried with anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified with silica gel column chromatography (35 g, ethyl acetate→ethyl acetate ethanol=10:1→ethyl acetate:ethanol triethylamine=100:10:0.5) and recrystallized from ethyl acetate/IPE to give 7-[4-(2-ethoxyethoxy)phenyl]-1-ethyl-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 16) (332 mg, 53%) as yellow crystals.
