| Reactant | Sodium Carbonate | HCID 10340 | — |
| Reactant | (R)-4-cyano-3-hydroxybutyric acid | HCID 10236005 | — |
| Product | Ethyl (3R)-4-cyano-3-hydroxybutanoate | HCID 2733879 | 90% |
Reaction Steps
(R)-4-cyano-3-hydroxybutyric acid (1.0 mol) in ethanol (500 ml) and conc. sulfuric acid (5 g) were refluxed for 5 hours. The reaction mixture was neutralized with sodium carbonate ancd filtered. The filtrate was concentrated in vacuo to afford (R)-4-cyano-3-hydroxybutyric acid ethyl ester (141 g, 90%).
