Reaction Conditions

Reaction Steps

To a stirred solution of methyl 5-bromo-2-methyl-3-nitrobenzoate (150 g, 544 mmol) in ethanol (750 mL), ammonium chloride (150 g, 2777 mmol) dissolved in water (750 mL) and iron powder (93.3 g, 1636 mmol) were added under stirring. Resulting reaction mass was heated at 80° C. for 7 h. On completion, reaction mass was filtered through celite giving washing of water and ethyl acetate, filtrate was extracted with ethyl acetate. Combined organic layers were dried, concentrated under reduced pressure giving the desired compound.
