To 7-bromo-N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (300 mg) were added toluene/ethanol/water (10/1/1, 19.2 ml) and then were added 4-(3-propoxypropoxy)phenyl borate (165 mg) and potassium carbonate (175 mg), and the mixture was stirred at room temperature for 30 minutes. To the mixture was added tetrakistriphenylphosphinepalladium (27 mg), and the mixture was refluxed for 14 hours and cooled to room temperature. The mixture was added to water, and the mixture was extracted with ethyl acetate/THF, washed with, saturated brine and dried with magnesium sulfate. Under reduced pressure, the solvent was evaporated, and the residue was purified with silica gel column chromatography (ethyl acetate/ethanol=3/1) and recrystallized from ethanol to give N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-7-[4-(3-propoxypropoxy)phenyl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 103) (245 mg).
