Hydrogen Bromide → 1-Methyl-3-bromopropyldiethylamine hydrobromide
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrogen Bromide | HCID 260 | — |
| Reactant | 1-Methyl-3-phenoxypropyldiethylamine | HCID 13520102 | — |
| Solvent | Chloroform | HCID 6212 | — |
| Product | 1-Methyl-3-bromopropyldiethylamine hydrobromide | HCID 20135845 | 78% |
Reaction Steps
5 g of the 1-methyl-3-phenoxypropyldiethylamine was reacted with 30 ml of 40% hydrobromic acid at 150° C. for 7 hours with stirring. The reaction solution was cooled and added with 20 ml of chloroform, and then the hydrobromic acid layer was separated from the chloroform layer. The hydrobromic acid was removed under reduced pressure and the residue was recrystallized from 5 ml of ethyl alcohol to give 4.88 g of 1-methyl-3-bromopropyldiethylamine hydrobromide in a yield of 78%.
