4.5 ml of hydrazine hydrate were added dropwise to the solution of 3.2 g of 4-fluoro-2-methoxynitrobenzene in 15 ml of N-methylpyrolidone and the mixture was stirred for 2 hours, which initially resulted in gentle heating. The mixture was then diluted with 50 ml of water and stirred, and a precipitate formed which was filtered off with suction and dried under reduced pressure.
