Reaction Steps

1-Bromo-3-(difluoromethyl)-5-nitrobenzene (944 mg, 3.60 mmol) was treated with iron powder (804 mg, 23.43 mmol) in a mixture of acetic acid (1.35 ml) and ethanol (25 ml) and stirred at 80° C. for 3 h. The crude was filtered over Celite and the solvent was removed in vacuum. A mixture of a solution of sodium bicarbonate 4% and ethyl acetate was added and the resulting mixture was filtered over Celite. The organic phase was washed with water and brine, dried over magnesium sulphate and the solvent was remove to give 855 mg (100% yield) of the title compound as a dark solid, that was used in the next step without further purification. Purity 96%.
