Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrogen Bromide | HCID 260 | — |
| Reactant | 1-Butyl-4-(4-methoxyphenyl)piperazine dihydrochloride | HCID 20519334 | — |
| Solvent | Acetic Acid | HCID 176 | — |
| Product | 4-(4-Butyl-1-piperazinyl)phenol monohydrobromide | HCID 20519295 | 81% |
Reaction Steps
A mixture of 12.5 parts of 1-butyl-4-(4-methoxyphenyl)-piperazine dihydrochloride and 150 parts of hydrobromic acid solution 48% in glacial acetic acid is stirred and refluxed overnight. The reaction mixture is evaporated and the residue is triturated in 2-propanone. The product is filtered off and crystallized from water, yielding 13.1 parts (81%) of 4-(4-butyl-1-piperazinyl)phenol monohydrobromide; mp. 281.9° C.
