Procedure

In toluene (15 ml), ethanol (1.5 ml) and water (1.5 ml) were suspended 7-propoxy-benzofuran-2-yl borate (165 mg), 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) and potassium carbonate (208 mg), and the suspension was stirred under argon atmosphere for 30 minutes. To the mixture was added tetrakistriphenylphosphinepalladium (47 mg), and the mixture was stirred, under argon atmosphere, at 100° C. for 8 hours and cooled. To the mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was 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 and recrystallized from ethanol to give colorless crystals of N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-1,1-dioxo-7-(7-propoxybenzofuran-2-yl)-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 143) (213 mg).
