Reaktionsschritte
To a solution of 2-bromo-1-phenyl-2-(phenylthio)ethanone (3.2 g) in N,N-dimethylformamide (25 mL) was added 2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)ethanethioamide (2.3 g) and the mixture was stirred at room temperature for 3 hr. A saturated aqueous sodium hydrogen carbonate solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated aqueous sodium hydrogen carbonate solution, water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was recrystallized from ethyl acetate-hexane to give the title compound as white crystals (yield 3.0 g, yield 71%).
