Reaction Steps

690 μL 3,4-difluoronitrobenzene was added to 15 mL anhydrous ethanol, and then the blend was heated to reflux. Hydrazine hydrate (611.5 μL) was slowly dropped into the blend and the resultant mixture was refluxed for another 2 hours to complete reaction, after which the reaction mixture was cooled down to room temperature. The yellow solid precipitated upon cooling was filtered. The filter cake was washed with petroleum ether, and then was dried to get 884.5 mg of a yellow solid, with a yield of 92.2%.
