Procedure

In water/ethanol/toluene(1:1:10, 18.0 ml) were dissolved 4-trifluoromethoxyphenyl borate (208 mg) and 7-bromo-1-methyl-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (407 mg), and to the mixture was added potassium carbonate (279 mg). Under argon atmosphere, the mixture was stirred for 30 minutes, and the mixture was added tetrakistriphenylphosphine palladium (39 mg). Under argon atmosphere, the mixture was refluxed for 16 hours, and the mixture was diluted with ethyl acetate (200 ml). The mixture was washed with water (50 ml) and saturated brine (50 ml), 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 (75 g, ethyl acetate→ethyl acetate/ethanol=20:1) and recrystallized from ethanol to give 1-methyl-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-7-(4-trifluoromethoxyphenyl)-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 315) (148 mg, 31%).
