Isopropanol → 2,3-Dicyano-5-chloro-6-isopropoxypyrazine
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Isopropanol | HCID 3776 | — |
| Reactant | 5,6-Dichloro-2,3-dicyanopyrazine | HCID 607820 | — |
| Product | 2,3-Dicyano-5-chloro-6-isopropoxypyrazine | HCID 12873752 | 45% |
Reaction Steps
Isopropanol (50 ml) was added to 1.99 g (0.01 mole) of 2,3-dicyano-5,6-dichloropyrazine, and the mixture was refluxed for 10 hours. After the reaction, the isopropanol was distilled off under reduced pressure. The crude product obtained (1.14 g) was chromatographed on a column of silica gel using benzene-n-hexane as an eluent to afford 1.00 g (yield 45%) of 2,3-dicyano-5-chloro-6-isopropoxypyrazine.
