Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2,6-Dichloropyrazine | HCID 78504 | — |
| Reactant | Potassium tert-butoxide | HCID 23665647 | — |
| Solvent | Tetrahydrofuran | HCID 8028 | — |
| Product | 2-tert-Butoxy-6-chloropyrazine | HCID 22248526 | 90% |
Reaction Steps
After dissolving 3.00 g of 2,6-dichloropyrazine in 40 ml of tetrahydrofuran, 2.26 g of potassium tert-butoxide was added and the mixture was stirred for 5.5 hours at room temperature. The reaction solution was distilled off under reduced pressure, ethyl acetate was added to the residue and filtration was performed with NH silica gel and silica gel. The solvent was distilled off under reduced pressure to obtain the title compound (3.38 g, 90% yield).
