Procedure

In water/ethanol/toluene (1:1:10, 18.0 ml) were dissolved 4-ethylthiophenyl borate (264 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 (439 mg), and to the mixture was added potassium carbonate (301 mg). Under argon atmosphere, the mixture was stirred for 30 minutes, and to the mixture was added tetrakistriphenylphosphine palladium (42 mg). Under argon atmosphere, the mixture was refluxed for 17.5 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→ethyl acetate/ethanol=9:1) and recrystallized from ethanol to give 7-(4-ethylthiophenyl)-1-methyl-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 320) (168 mg, 34%).
