|---|---|---|---|
| Reactant | 2-Bromo-4'-(trifluoromethyl)acetophenone | HCID 321979 | — |
| Reactant | Sodium Formate | HCID 2723810 | — |
| Solvent | Methanol | HCID 887 | — |
| Product | 2-Hydroxy-1-[4-(trifluoromethyl)phenyl]ethan-1-one | HCID 11287169 | 80.1% |
Reaction Steps
A mixture of 2-bromo-4′-trifluoromethyl acetophenone (40.0 g), sodium formate (40.0 g) and methanol (200 ml) was stirred with heating under reflux for 6 hours. The reaction mixture was concentrated and poured into water (500 ml). The precipitated crystals were filtered, washed with water, and air-dried to give crystals of 2-hydroxy-4′-trifluoromethyl acetophenone (24.5 g, 80%). Melting point 112-114° C.
