Potassium Carbonate → HCID 9830715, compound

Participants

Reaction Steps

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), 4-[N-methyl-N-(2-propoxyethyl)amino]phenyl borate (205 mg) and potassium carbonate (176 mg) in toluene/ethanol/water (10/1/1 ml) was stirred at room temperature for 1 hour. To the mixture was added tetrakistriphenylphosphinepalladium (40 mg), and the mixture was refluxed for 8 hours, cooled, extracted with ethyl acetate, washed with saturated brine, dried with magnesium sulfate and was 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 pale yellow crystals of 7-[4-[N-methyl-N-(2-propoxyethyl)amino]phenyl]-N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 72) (210 mg).
