Reaktionsschritte

In a 300 ml-three-necked flask, 5.00 g (27.6 mM) of 2-nitro-4-acetylphenol was 75 ml of 2N-sodium hydroxide aqueous solution were placed. To the mixture, a solution of 25.00 g of sodium hydrosulfite (Na2S2O4) in 75 ml of water was added dropwise in 10 minutes, followed by stirring for 20 minutes at room temperature to precipitate a crystal. The crystal was recovered by filtration and recrystallized from a mixture solvent (methanol-water) to obtain 1.63 g of 2-amino-4-acetylphenol (Yield: 39.1%).
