Participants

Reaction Steps

5-Methoxycarbonylthieno[2,3-b]thiophene-2-sulfonamide (0.55 g., 2 mmoles) and 3-(methoxyethoxy)propylamine (0.80 g., 6 mmoles) were refluxed in methanol (5 mL) for 96 hours. The solution was cooled and evaporated in vacuo to remove most of the methanol. Ether was added and the resulting product was recrystallized from 1,2-dichloroethane to give 0.49 g of 5-(N-methoxyethoxypropylcarbamoyl)thieno[2,3-b]thiophene-2-sulfonamide, m.p. 154°-155° C.
