Chloroacetyl chloride → 1-(2-Chloro-acetyl)-pyrrolidin-2-one
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Chloroacetyl chloride | HCID 6577 | — |
| Reactant | 2-Pyrrolidone | HCID 12025 | — |
| Solvent | Toluene | HCID 1140 | — |
| Product | 1-(2-Chloro-acetyl)-pyrrolidin-2-one | HCID 3161251 | 97% |
Reaction Steps
To an initial charge of 81.0 g of 2-pyrrolidone in 200 ml of toluene there are added, dropwise and with ice cooling, 54.7 g of chloroacetyl chloride such that the temperature of the reaction mixture remains at 5° C. Following the addition the reaction mixture is stirred at room temperature for 6 hours. The resulting precipitate is filtered off with suction and the solvent is removed in vacuo to give 74.5 g of N-(chloroacetyl)pyrrolidone, corresponding to a yield of 97%.
