Versuchsvorschrift

In a 300 ml three-neck flask, 5.00 g (27.6 m mole) of 2-nitro-4-acetylphenol and 75 ml of 2N-sodium hydroxide solution were placed. To the mixture solution, a solution, which 25.00 g of sodium hydrosulfite was dissolved in 75 ml to water, was added dropwise in 10 minutes. Then the mixture solution was stirred for 20 minutes at room temperature to precipitate a crystal. The crystal was filtered and recrystallized from a mixture solvent of methanol-water to obtain 1.63 g of 2-amino-4-acetylphenol (Yield: 39.1%).
