Versuchsvorschrift

A mixture of 283 g of 2,2-dimethyl-4-(p-methoxyphenyl)-3-(N-methyl-p-toluenesulfonamido)butyric acid, 1500 ml of dry benzene and 430 ml of thionyl chloride is boiled for 3 hours. After removal of volatile material by evaporation in vacuo, the residue is taken up in toluene and the solvent is evaporated in vacuo. This procedure is repeated twice whereafter crystallization of the initially oily product is accomplished by treatment with ether, melting point 110°-111° C.
