Procedure
Sodium periodate (1.40 g., 6.54 mmoles) was dissolved in water (20 mL). THF (20 mL) was added followed by 5-[N-(3-thia-n-butyl)carbamoyl]thieno[2,3-b]thiophene-2-sulfonamide (1.10 g., 3.27 mmoles) were stirred at room temperature under Argon for 24 hours. The solution was filtered and then stripped of the THF and all but 2-2 mL of water. The product was then crystallized, collected and dried. Recrystallization from nitromethane gave 1.0 g. of 5-[N-(3-oxo-3-thia-n-butyl)carbamoyl]thieno[2,3-b]thiophene-5-sulfonamide, mp 242°-243° C.
