Versuchsvorschrift

5 g of the 1-methyl-3-phenoxypropyldimethylamine thus obtained was reacted with 30 ml of 40% hydrobromic acid at 150° C. for 7 hours with stirring. The reaction solution was cooled, 20 ml of chloroform was added and then the solution was separated. The hydrobromic acid was removed under reduced pressure and the residue was recrystallized from 5 ml of ethyl alcohol to give 4.46 g of 1-methyl-3-bromopropyldimethylamine hydrobromide in a yield of 79%.
