Versuchsvorschrift

100 g of [{1-(1,3-benzodioxol-5-yl)butyl}thio] acetic acid was dissolved in 500 ml of ethanol. 372 ml of 1N-aqueous sodium hydroxide solution was added thereto. Ethanol and water were removed from the reaction mixture by azeotropic distillation and then ether was added to the residue to solidify it. A precipitate thus formed was recovered by filtration and dried to obtain 102 g of the intended compound in the form of a white powder.
