Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 1-Bromo-2-butanone | HCID 13156 | — |
| Reactant | 4-Hydroxythiobenzamide | HCID 2759344 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | HCID 136403366 | HCID 136403366 | 65.2% |
Reaction Steps
A mixture of 4.6 parts of 4-hydroxybenzothioamide, 4.5 parts of 1-bromo-2-butanone and 79 parts of ethanol was stirred for 5 hours at reflux temperature. After cooling, the precipitate was filtered off and dried in vacuo at 50° C., yielding 5.6 parts (65.2%) of 4-(4-ethyl-2-thiazolyl)phenol hydrobromide (interm. 14).
