Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethyl bromoacetate | HCID 7748 | — |
| Reactant | N-Ethylpiperidine | HCID 13007 | — |
| Solvent | Dichloromethane | HCID 6344 | — |
| Product | 1-(2-Ethoxy-2-oxoethyl)-1-ethylpiperidin-1-ium bromide | HCID 3048283 | 98.6% |
Reaction Steps
To a solution of 1-ethylpiperidine (2.5 g, 22.1 mmol) in dichloromethane (4 mL) was added ethylbromoacetate (3.7 g, 22.1 mmol) via a syringe. The mixture was stirred at room temperature overnight. The resulting white precipitate was washed with hexane and ethylacetate to give 6.1 g, 98.6% yield of the product as a white solid. Positive mode ESI/MS: m/z=200.4 (M+, minus Br); confirmed by 1H NMR.
