Versuchsvorschrift

27 g of 2-isopropylbenzenesulfonyl chloride and 22 g of KF are stirred in 75 ml of dioxane and 20 ml of water at 45° C. for 27 h and at RT for 45 h. 800 ml of water are then added, and the mixture is extracted with 3×300 ml of EA. The combined organic phases are dried over Na2SO4 and the solvent is removed in vacuo. 24 g of a colorless oil are obtained.
