Versuchsvorschrift

To a solution of 41.39 g of 3-acetyl indole in 300 ml of dimethyl sulfoxide at 0° C. was added a solution of 18.6 g of potassium hydroxide in 20 ml of water. This mixture was stirred at 0° C. for 2 hours, then 47.6 ml of benzenesulfonyl chloride was added dropwise over 40 minutes. The mixture was stirred for an additional 30 minutes, then poured into aqueous ammonium chloride and extracted several times with ether. The ether extracts were combined, washed with water, dried and evaporated, giving 59.8 g of 3-acetyl-N-phenylsulfonyl indole.
