実験手順
A mixture of 7-bromo-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (0.3 g), 4-(3-ethoxypropyl)phenyl borate (0.18 g), 1M potassium carbonate solution (1.3 ml), ethanol (1.3 ml) and toluene (25 ml) was stirred under argon atmosphere at room temperature for 30 minutes. To the mixture was added tetrakistriphenylphosphinepalladium (0.03 g), and the mixture was refluxed under argon atmosphere for 6 hours and extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried with anhydrous magnesium sulfate. The solvent was evaporated, and the residue was purified with silica gel column chromatography (ethyl acetate/methanol/triethylamine) to give crude crystals, which were recrystallized from ethanol to give 7-[4-(3-ethoxypropyl)phenyl]-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 123) (0.25 g) as colorless crystals.
