Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 3'-Fluoro-4'-methoxy-[1,1'-biphenyl]-4-carboxylic acid | HCID 1203166 | — |
| Solvent | Hydrogen Bromide | HCID 260 | — |
| Solvent | 1,4-Dioxane | HCID 31275 | — |
| Product | 4-(3-Fluoro-4-hydroxyphenyl)benzoic acid | HCID 836139 | 95.1% |
Reaction Steps
Subsequently, 6.8 g of 3'-fluoro-4'-methoxybiphenyl-4-carboxylic acid was heated under reflux for 14 hours in 150 ml of 48% hydrobromic acid and 80 ml of dioxane. The volatile components were removed by evaporator, and the residue was washed several times with water to give 6.10 g (yield 95%) of the desired 3'-fluoro-4'-hydroxybiphenyl-4-carboxylic acid.
