Versuchsvorschrift

333 mg of 2-chloro-3-[4-(2-methyl-2-phenylpropyloxy) phenyl]propionic acid and 150 mg of thiourea are heated with 2 ml of sulfolane at 120° C. for 1.5 hours and, following the addition of 2 ml of 6 N--HCl, the mixture is further heated for 5 hours, at the end of which time 10 ml of water is added. The resulting crystals are recovered by filtration. By the above procedure is obtained 310 mg of 5-[4-(2-methyl-2-phenylpropyloxy)benzyl]thiazolidine-2,4-dione.
