Reaktionsschritte

In 2 ml of dimethylsulfoxide are dissolved 200 mg of 2-bromo-3-[4-(4-chlorobenzyloxy)phenyl]propionic acid and 100 mg of thiourea and the solution is heated at 110° C. for 3 hours. Then, after 0.5 ml of water is added, the solution is further heated for 5 hours. Then, 10 ml of water is added and the resulting crystals are recovered by filtration and recrystallized from benzene-n-hexane (1:1). By the above procedure is obtained 170 mg of 5-[4-(4-chlorobenzyloxy)benzyl]thiazolidine-2,4-dione.
