Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methyl iodide | HCID 6328 | — |
| Reactant | Acetamidomalonic acid diethyl ester | HCID 14041 | — |
| Reactant | Sodium hydride | HCID 24758 | — |
| Solvent | Tetrahydrofuran | HCID 8028 | — |
| Product | HCID 575660 | HCID 575660 | 77.9% |
Reaction Steps
To a solution of diethyl 2-acetylaminomalonate (2.17 g) in dry tetrahydrofuran is added sodium hydride (0.26 g), and the mixture is stirred at room temperature for one hour. After stirring, methyl iodide (1.60 g) is added dropwise thereto, and the mixture is stirred overnight. The reaction mixture is concentrated, and to the residue is added ethyl acetate and water. The organic layer is separated, dried and evaporated to remove the solvent. The residue is recrystallized from a mixture of isopropyl ether and n-hexane to give diethyl 2-acetylamino-2-methylmalonate (1.80 g), m.p. 89°-90° C.
