Reaction Steps

1.9 g Of ethyl 3-[4-(2-methyl-2-phenylpropyloxy)phenyl]-2-thiocyanatopropionate is dissolved in 20 ml of ethanol and to the solution 20 ml of 6 N-hydrochloric acid is added. The mixture is refluxed for 24 hours. After cooling, water is added to the mixture. The mixture is subjected to extraction with ether. The extract is washed with water and then dried. After distilling off ether, the residue is crystallized from ether-n-hexane, whereby 730 mg of 5-[4-(2-methyl-2-phenylpropyloxy)benzyl]thiazolidine-2,4-dione is obtained.
