Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Acetic Anhydride | HCID 7918 | — |
| Reactant | Ethyl 2-(piperidin-4-yl)acetate | HCID 2760465 | — |
| Solvent | Toluene | HCID 1140 | — |
| Product | Ethyl 1-acetyl-4-piperidineacetate | HCID 54363171 | 82% |
Reaction Steps
A mixture of 200 parts of acetic acid anhydride, 90 parts of ethyl 4-piperidineacetate and 225 parts of methylbenzene is stirred and refluxed for 3 hours. The reaction mixture is evaporated and the residue is diluted with water. The product is extracted with methylbenzene. The extract is dried, filtered and evaporated, yielding 92 parts (82%) of ethyl 1-acetyl-4-piperidineacetate as a residue.
