Procedure
Under argon atmosphere, a mixture of 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), 3-chloro-4-ethoxyphenyl borate (127 mg) and potassium carbonate (160 mg) in toluene/ethanol/water (10/1/1 ml) was stirred at room temperature for 1 hour. To the mixture was added tetrakistriphenylphosphinepalladium (33 mg), and the mixture was refluxed for 30 hours, cooled, extracted with ethyl acetate, washed with saturated brine, dried with magnesium sulfate and concentrated under reduced pressure. The residue was purified with silica gel column chromatography (ethanol/ethyl acetate=1:4) to give crystals, which were recrystallized from ethanol to give colorless crystals of 7-(3-chloro-4-ethoxyphenyl)-N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 49) (38 mg).
