Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Sodium ethoxide | HCID 2723922 | — |
| Reactant | 6-Chloro-3-pyridinecarbonitrile | HCID 5152094 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 6-Ethoxypyridine-3-carbonitrile | HCID 18929445 | 83.4% |
Reaction Steps
Add sodium ethoxide (1.6 mL of 21% w/v in ethanol, 4.8 mmol) to a solution of 6-chloronicotinonitrile (612 mg, 4.41 mmol) in anhydrous ethanol (15 mL) and heat the reaction at reflux for 3 h. Cool to room temperature and stir overnight under nitrogen atmosphere. Concentrate in vacuo and dissolve the residue into dichloromethane. Wash with saturated aqueous NaHCO3, dry over MgSO4 and concentrate in vacuo to give the desired intermediate as an off-white solid (545 mg, 83%).
