反応手順
A solution of 29.6 g. (0.20 mole) of p-nitrobenzonitrile, 13.9 g. (0.20 mole) of hydroxylamine HCl, 13.8 g. (0.10 mole) of K2CO3 in 700 ml. of ethanol and 70 ml. of water is refluxed for 20 hours, cooled and diluted with 200 ml. of water. After removal of the ethanol by distillation in vacuo, the product is collected by filtration, washed with water and dried to yield 21.6 g. (60%).
