Versuchsvorschrift

In a mixture of water ethanol toluene (1:1:10, v/v, 18.0 ml) were dissolved 4-(3-propoxy)propoxyphenyl borate (270 mg) and 7-bromo-1-formyl-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (377 mg). To the solution was added potassium carbonate (251 mg), and the mixture was stirred under argon atmosphere at room temperature for 30 minutes. To the mixture was added tetrakistriphenylphosphinepalladium (35 mg), and the mixture was heated to reflux under argon atmosphere for 10 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 (25 g, ethyl acetate→ethyl acetate:ethanol=10:1→ethyl acetate:ethanol:triethylamine=100:10:0.5) and recrystallized from ethanol to give 1-formyl-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-7-[4-(3-propoxy)propoxyphenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 22) (304 mg, 66%) as white crystals.
