A 100 g (0.48 mol) portion of phosphorus pentachloride is added to a flask containing 82.0 g (0.4 mol) of the above sulfonic acid salt. When the initial reaction subsides, the mixture is heated on the steam bath for 1 hr and 25 g of phosphorus pentachloride is added. Heating is continued for another 2.5 hr and another 10 g of phosphorus pentachloride is added and heating continued for 30 min. The dark reaction mixture is cooled and filtered and the filtrate distilled. The clear distillate is redistilled to give 42.3 g of 3-acetyloxy-1-propanesulfonyl chloride; bp 69°-81°/0.03 mm.
