2-Bromo-1-(4-hydroxyphenyl)ethanone → HCID 19773531, compound
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2-Bromo-1-(4-hydroxyphenyl)ethanone | HCID 4964 | — |
| Reactant | Propanethioamide | HCID 2760628 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | HCID 19773531 | HCID 19773531 | 40.2% |
Reaction Steps
A mixture of 3.6 parts of propanethioamide, 8.6 parts of 2-bromo-1-(4-hydroxyphenyl)ethanone and 79 parts of ethanol was stirred for 7 hours at reflux temperature. The reaction mixture was concentrated to 1/4 of its volume and 2,2'-oxybispropane was added to the residue. The precipitate was filtered off and taken up in water. After basifying with NH4OH, the product was extracted with dichloromethane. The extract was dried, filtered and evaporated, yielding 3.3 parts (40.2%) of 4-(2-ethyl-4-thiazolyl)-phenol (interm. 17).
