2,2,2-Trifluoroethanol → 3-Bromo-5-(2,2,2-trifluoroethoxy)pyridine
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2,2,2-Trifluoroethanol | HCID 6409 | — |
| Reactant | 3,5-Dibromopyridine | HCID 69369 | — |
| Product | 3-Bromo-5-(2,2,2-trifluoroethoxy)pyridine | HCID 22570352 | 70% |
Reaction Steps
2,2,2-Trifluoroethanol and 3,5-dibromopyridine were processed as described in Example 7A except that the heating time was extended to 20 hours at 100° C. The reaction was quenched onto ice/water, extracted with ethyl ether, and concentrated. The residue was purified on silica gel (hexanes:ethyl acetate, 8:2) to provide the title compound as a colorless oil (70% yield). MS (DCI/NH3) m/z 256/258 (M+H)+.
