The product from Example 1 (1 g) was added to 8 mL of trifluoroacetic acid, and the clear solution was stirred at room temperature for 4-5 hours. Removal of the volatiles in vacuo afforded an orange oil, which was subjected to silica gel chromatography. Elution with 4:1 hexane/ethyl acetate gave 650 mg of the title sulfonamide as a white powder, m.p. 76°-79° C.; IR (nujol): 1720, 1730, 3290, 3400 cm-1.
