Versuchsvorschrift
Preparation analogously to Example 70 by the reaction of 3-dimethylaminophenol sodium salt with 3-chloro-1-propanol to give 3-(3-dimethylaminophenoxy)-1-propanol (b.p.0.7 =150°-5°; yield 57%), which is converted quantitatively into 3-(3-dimethylaminophenoxy)-propyl 1-methanesulphonate (oil) and is reacted with excess 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol 2-nitrate in boiling ethanol. Isolation as hydrochloride. Yield, after recrystallisation from ethanol+active charcoal: 38.2%.
