Ethyl 3-oxobutanoate sodium salt synthesis
- Product Name:Ethyl 3-oxobutanoate sodium salt
- CAS Number:15933-07-0
- Molecular formula:C6H10O3
- Molecular Weight:130.14
Yield:15933-07-0 98%
Reaction Conditions:
sulfuric acid for 4 h;Reflux;
Steps:
23.W.b
b. Ethyl 2-oxobutanoate To a solution of 2-oxobutanoic acid (6.0 g, 58.8 mmol) in EtOH (100 mL) was added sulfuric acid (1 mL) at room temperature. The resulting mixture was stirred for 4 h under reflux. The solvent was removed, and the residue was diluted with water (50 mL) and the pH was adjusted to ~7 with a solution of NaOH (1 N). The mixture was extracted with EtOAc (100 mL*3). The combined organic layer was dried over sodium sulfate and concentrated to give ethyl 2-oxobutanoate (7.5 g, 98% yield). ESI MS: m/z 131 [M+H]+.
