Participants
| Role | Name | HCID | Charge |
|---|
| Reactant | Propylenediamine | HCID 6567 | — |
| Reactant | Dimethyl itaconate | HCID 69240 | — |
| Product | 5-Oxo-pyrrolidine-3-carboxylic acid methyl ester | HCID 13118117 | — |
Reaction Steps
Equimolar amounts of N-allyl, N-methyl, propylene diamine prepared as described above and Dimethyl Itaconate are charged to a reaction vessel and heated slowly with agitation to 130°-150° C. After the exotherm subsides, the reaction mixture is maintained at 140° C. for 3 hours. The reaction product 1-(N-allyl, N-methyl aminopropyl)-4-carbomethoxy pyrrolidone is isolated by distillation.
