Reaction Steps

Ethyl 2-(4-bromo-2-nitroanilino)-5-ethyl-thiophene-3-carboxylate (0.4 g, 0.001 mol) was added to powdered zinc (0.4 g) and ammonium chloride (0.4 g) in water (10 ml) and stirred at 50° C. for 24 hours. The reaction mixture was filtered and the recovered solid washed successively with water and ethyl acetate. The organic phase was separated, washed with water, dried (MgSO4) and evaporated in vacuo to give the title compound.
