Reaction Steps

Methyl 4-bromo-3-(1-methylethoxy)-5-phenyl-2-thiophenecarboxylate (4.8 g, 14 mmoles) is stirred in methanol (5 mL), 1N NaOH (27 mL) is added, and the mixture is stirred and heated under reflux. After 3 hours the mixture is stirred into water (300 mL) and acidified with concentrated HCl. The precipitate is filtered off, rinsed with water and dried to afford the product (4.7 g); mp 159°-160° C.
