실험 절차

28 g (0.1 mol) of 2-chloro-5-nitrophenyl 2-hydroxypropyl sulphone are refluxed in 100 ml of isopropanol. To this are added gradually 15 ml of ethylenediamine, and heating is continued with stirring for a further hour. The cold reaction solution is diluted with 300 ml of water and stirred at 20° C. for two hours. The precipitated yellowish crystals are filtered off with suction, washed with 100 ml of water and dried. This gives 28 g of uniform 2-(2-aminoethylamino)-5-nitrophenyl 2-hydroxypropyl sulphone.
