Reaction Steps

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), 3,4-dipropoxyphenyl borate (0.17 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 tetrakis(triphenylphosphine)palladium (0.03 g), and the mixture was refluxed under argon atmosphere for 6 hours and extracted with ethyl acetate. The organic layer washed with water and saturated brine and dried with anhydrous magnesium sulfate, and the solvent was evaporated. 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-(3,4-dipropoxyphenyl)-N-(4-((N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino)methyl)phenyl)-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 155) (0.27 g) as colorless crystals.
