Procedure

To 7-bromo-N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (0.41 g) was added toluene/ethanol/water (10/1/1,19.2 ml) and then were added 2-(propoxymethyl)-1-benzofuran-5-yl borate (0.22 g) and potassium carbonate (0.24 g), and the mixture was stirred at room temperature for 30 minutes. To the mixture was added tetrakistriphenylphosphinepalladium (45 mg), and the mixture was refluxed for 14 hours, cooled to room temperature and poured into water. The mixture was extracted with ethyl acetate, washed with saturated brine and dried with magnesium sulfate. Under reduced pressure, the solvent was removed, and the residue was purified with silica gel column chromatography (ethyl acetate/ethanol=4/1) and recrystallized from ethanol to give N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-7-[2-(propoxymethyl)-1-benzofuran-5-yl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 136) (184 mg).
