The product from Example 5 (13.8 g) was added in portions to 75 ml of trifluoroacetic acid at room temperature and the resulting solution was stirred for 21 hours. Removal of the trifluoroacetic acid in vacuo gave a light orange oil which crystallized upon addition of diethyl ether. Filtration and air drying yielded 9.18 g of pure 2-[2-(acetyloxy)ethyl]benzenesulfonamide as a white powder, m.p. 116°-117.5° C.
