In water/ethanol/toluene (1:1:10, 18.0 ml) were dissolved 4-(1-piperidinyl)phenyl borate (179 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 (353 mg), and to the mixture was added potassium carbonate (242 mg). Under argon atmosphere, the mixture was stirred for 40 minutes, and to the mixture was added tetrakistriphenylphosphine palladium (34 mg). Under argon atmosphere, the mixture was ref luxed for 15 hours, and the mixture was dilute 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/ethanol=9:1) and recrystallized from ethanol to give 1-methyl-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]-phenyl]-7-[4-(1-piperidinyl)phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 316) (79 mg, 19%).
