Reaktionsschritte

A little at a time, 1.3 g (8.4 mmol) of 1,3-thiazolidine-2,4-dione potassium salt were added to a solution of 2.0 g (8.2 mmol) of 2-bromo-1-(4-nitrophenyl)ethanone in 80 ml of acetone, and the mixture was stirred at 60° C. for 1 h. The reaction mixture was concentrated under reduced pressure and the residue was dissolved in water/dichloromethane. After phase separation, the organic phase was dried (sodium sulphate), filtered, concentrated under reduced pressure and dried. Yield: 2.3 g (98% of theory)
