Versuchsvorschrift

In water:ethanol:toluene (1:1:10, 18.0 ml) were dissolved 4-ethylphenyl borate (227 mg) and 7-bromo-1-methyl-N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]-methyl]phenyl]-2,3-dihydro-1-benzoazepine-4-carboxamide (611 mg), and to the mixture was added potassium carbonate (418 mg). The mixture was stirred under argon atmosphere for 30 minutes, and to the mixture was added tetrakistriphenylphosphine palladium (59 mg). Under argon atmosphere, the mixture was refluxed for 17 hours, and the mixture was diluted with ethyl acetate (200 ml) and washed with water (50 ml) and saturated brine (50 ml). The organic layer was dried with anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified with silica gel column chromatography (75 g, ethyl acetate:ethanol=9:1) and recrystallized from ethanol to give 7-(4-ethylphenyl)-1-methyl-N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1-benzoazepine-4-carboxamide (Compound 307) (252 mg, 39%).
