Versuchsvorschrift
In 3 liters of ethanol were dissolved 330 g of m-amino-phenol and the resulting solution was boiled under reflux and to this solution were added 360 g of propanesultone all together. Continuation of the reflux yielded gradually white powdery crystal. After refluxing for 5 hours, the reaction solution was cooled with ice and the yielded white powdery crystal was collected by filtration and washed several times with ethanol. The yield was 146 g and the melting point was above 250° C.
