실험 절차

In a solution of 5.0 g of 4-bromo-3-nitrobenzaldehyde in 50 ml of methanol, 3.6 ml of 50% hydroxyamine aqueous solution was added with stirring at room temperature, and continued to stir at the same temperature for 18 hours. After the completion of the reaction, 60 ml of water was added in the reaction mixture, and precipitated solid was filtered off, washed with water and then dried to obtain 5.0 g of the aimed product as yellow crystal.
