Reaction Conditions

Reaction Steps

To stirred solution of above crude 2-bromo-3-nitrobenzoate (4 g, 15.38 mmol) in ethanol (20 mL), ammonium chloride (4 g, 74.0 mmol) dissolved in water (20 mL) and iron powder (6.87 g, 123 mmol) were added under stirring. The resulting reaction mixture was heated at 80° C. for 7 h. On completion, the reaction mixture was filtered through celite, washing with water and ethyl acetate and the filtrate extracted with ethyl acetate. The combined organic layers were dried and concentrated under reduced pressure giving the desired crude product (3 g).
