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), 3,4-dihydro-2H-1-benzopyran-6-yl borate (113 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, 0.029 mmol), and the mixture was refluxed for 6 hours, cooled, extracted with ethyl acetate, washed with saturated brine, dried with magnesium sulfate and concentrated under reduced pressure to give crystals, which were collected by filtration and recrystallized from ethanol to give pale yellow crystals of 7-(3,4-dihydro-2H-1-benzopyran-6-yl)-N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 62) (149 mg).
