Versuchsvorschrift

0.05 mol (10.6 g) of 2,6-dinitro-4-methylanisole is dissolved in 50 ml of absolute alcohol. 0.1 mol (9.1 g) of 1-aminopropane-2,3-diol is added gradually to this solution, whilst stirring. The solution is heated under reflux for 3 hours 30 minutes. The alcohol is driven off in vacuo and 40 ml of iced water are added to the residual red oil. The expected product crystallises. It is filtered off and washed with water. After recrystallisation from an aqueous-alcoholic mixture and drying in vacuo, it melts at 118° C.
